### In Quadrant 1, what transformations are applicable:

• A.

X squared

• B.

Y squared

• C.

Reciprocal x

• D.

Reciprocal y

• E.

Log x

• F.

Log y

A. X squared
B. Y squared
Explanation
The transformations that are applicable in Quadrant 1 are x squared and y squared. This means that the values of x and y are squared, resulting in a positive value for both x and y. The reciprocal transformations (reciprocal x and reciprocal y) would not be applicable in Quadrant 1 because they would result in negative values for x or y. Similarly, the logarithmic transformations (log x and log y) would also not be applicable in Quadrant 1 as they would result in undefined or negative values for x or y.

Explanation
In Quadrant 2, the transformations that are applicable are y squared, reciprocal x, and log x. When a function is squared, it reflects across the x-axis, resulting in a positive y-value. The reciprocal of x reflects the function across the y-axis, while the logarithm of x reflects it across the y-axis as well, but with a different rate of change. These transformations help to understand the behavior of the function in Quadrant 2.

Explanation
In Quadrant 3, the x-coordinate is negative while the y-coordinate is positive. The reciprocal of a negative number is also negative, so the transformation of reciprocal x is applicable in Quadrant 3. Similarly, the reciprocal of a positive number is positive, so the transformation of reciprocal y is applicable in Quadrant 3. Additionally, logarithmic functions are defined for positive numbers, so the transformations of log x and log y are also applicable in Quadrant 3.

### In Quadrant 4, what transformations are applicable:

• A.

X squared

• B.

Y squared

• C.

• E.

Log x

• F.

Log y

A. X squared
D. Reciprocal y
F. Log y
Explanation
In Quadrant 4, the x-values are positive and the y-values are negative. Therefore, the transformations that are applicable in this quadrant are x squared (which keeps the x-values positive), reciprocal y (which changes the sign of the y-values), and log y (which is only defined for negative y-values).

### Which Quadrants are appropriate for an x squared transformation

• A.

• B.

• C.

• D.

Explanation
The appropriate quadrants for an x squared transformation are Quadrant 1 and Quadrant 4. In Quadrant 1, both the x and y coordinates are positive, and when x is squared, the resulting y value will also be positive. In Quadrant 4, the x coordinate is positive and the y coordinate is negative, and when x is squared, the resulting y value will still be positive. Therefore, the x squared transformation is appropriate for these two quadrants.

Rate this question:

• 6.

### Which Quadrants are appropriate for a y squared transformation

• A.

• B.

• C.

• D.

Explanation
A y squared transformation refers to a transformation in which the y-coordinate of a point is squared. In this transformation, the sign of the y-coordinate does not change, but its value is squared. Since squaring a positive number results in a positive number, Quadrant 1 and Quadrant 2 are appropriate for a y squared transformation. In these quadrants, the y-coordinates are positive, and squaring them will still yield positive values. Quadrant 3 and Quadrant 4, on the other hand, have negative y-coordinates, and squaring them will result in positive values, which is not appropriate for a y squared transformation.

Rate this question:

• 7.

### Which Quadrants are appropriate for a log x transformation

• A.

• B.

• C.

• D.

Explanation
A log x transformation is appropriate for Quadrant 2 and Quadrant 3. In Quadrant 2, the x-values are negative and the y-values are positive, while in Quadrant 3, both the x-values and y-values are negative. A log x transformation is used to transform skewed data with positive and negative values into a more symmetrical distribution. Therefore, Quadrant 2 and Quadrant 3 are appropriate for a log x transformation.

Rate this question:

• 8.

### Which Quadrants are appropriate for a log y transformation

• A.

• B.

• C.

• D.

Explanation
A log y transformation is appropriate for Quadrant 3 and Quadrant 4. This is because in these quadrants, the y-values are negative or zero, which cannot be directly plotted on a logarithmic scale. By applying a log y transformation, the negative or zero values can be transformed into positive values, allowing them to be plotted on a logarithmic scale. Quadrant 1 and Quadrant 2 have positive y-values, which can be directly plotted on a logarithmic scale without the need for a transformation.

Rate this question:

• 9.

### Which Quadrants are appropriate for a 1/y transformation

• A.

• B.

• C.

• D.

Explanation
A 1/y transformation involves taking the reciprocal of the y-coordinate of a point. When we take the reciprocal of a positive y-coordinate, the resulting value will be positive. Therefore, points in Quadrant 1 and Quadrant 2, where the y-coordinates are positive, are not appropriate for a 1/y transformation. However, in Quadrant 3 and Quadrant 4, where the y-coordinates are negative, taking the reciprocal will result in positive values. Hence, Quadrant 3 and Quadrant 4 are appropriate for a 1/y transformation.

Rate this question:

• 10.

### Which Quadrants are appropriate for a 1/x transformation

• A.

• B.

• C.

• D.

Explanation
A 1/x transformation is appropriate for Quadrant 2 and Quadrant 3. In Quadrant 2, the x-values are positive while the y-values are negative, which allows for the transformation to be applied. In Quadrant 3, both the x-values and y-values are negative, also allowing for the transformation. In Quadrant 1, both x-values and y-values are positive, which does not fit the criteria for a 1/x transformation. In Quadrant 4, the x-values are negative while the y-values are positive, which also does not fit the criteria.

### What is the effect of transformations in Quadrant 1

• A.

They stretch x values

• B.

They stretch y values

• C.

They compress x values

• D.

They compress y values

A. They stretch x values
B. They stretch y values
Explanation
Transformations in Quadrant 1 refer to the changes in the coordinates of a point in the Cartesian plane when it is subjected to certain operations. In this case, the effect of these transformations is to stretch both the x and y values. This means that the x and y coordinates of a point will be multiplied by a factor greater than 1, resulting in a larger distance from the origin in both the horizontal and vertical directions. This stretching effect is characteristic of transformations in Quadrant 1.

### What is the effect of transformations in Quadrant 2

• A.

They stretch x values

• B.

They stretch y values

• C.

They compress x values

• D.

They compress y values

B. They stretch y values
C. They compress x values
Explanation
Transformations in Quadrant 2 refer to changes made to the coordinates of points in the second quadrant of a coordinate plane. In this quadrant, the x values are negative and the y values are positive. The given answer states that transformations in Quadrant 2 stretch the y values and compress the x values. This means that the y values of the points will be multiplied by a factor greater than 1, causing them to increase in magnitude, while the x values will be multiplied by a factor between 0 and 1, causing them to decrease in magnitude.

### What is the effect of transformations in Quadrant 3

• A.

They stretch x values

• B.

They stretch y values

• C.

They compress x values

• D.

They compress y values

C. They compress x values
D. They compress y values
Explanation
Transformations in Quadrant 3 refer to the region of the coordinate plane where both the x and y values are negative. In this quadrant, the x values and y values are compressed, meaning they are scaled down or reduced in size. This can be visualized as a shrinking or narrowing effect on the coordinate points in Quadrant 3. Therefore, the correct answer is that transformations in Quadrant 3 compress both the x values and y values.

### What is the effect of transformations in Quadrant 4

• A.

They stretch x values

• B.

They stretch y values

• C.

They compress x values

• D.

They compress y values

A. They stretch x values
D. They compress y values
Explanation
Transformations in Quadrant 4 have the effect of stretching x values and compressing y values. This means that the x-coordinates of the points in the graph will be stretched horizontally, making the graph wider. On the other hand, the y-coordinates of the points will be compressed vertically, making the graph shorter. This can be visualized as a horizontal stretching and vertical compression of the graph in Quadrant 4.
