Assessment for POLAHS precalculus students. This is the assessment for chapters 1 and 2 from our textbook.

• 1.

### Can you identify the equations of all of the different colored functions in the graph below? All are related with only minor adjustments to the "parent function". If you need some help to get started, the "parent function" is one of the equations from a previous question. Your tasks:Â  #1)Â  Enter the equation for each of the 5 different functions on the coordinate plane below.Â Â Â Â Â  Â  #2)Â  Identify which function (by equation and by color),Â  I used as the "parent function."

• D.

{(2, 0), (3, 2), (4, 0)}

• E.

{(1, 2), (3, 0), (1, â€“2), (3, 2)}

D. {(2, 0), (3, 2), (4, 0)}
• 4.

### Which equation does not represent y as a function of x?

• A.

8y = 5

• B.

â€“4x = â€“4y

• C.

â€“3x â€“ 8y = 4

• D.

â€“9x^2 + 8y = 6

• E.

2y^2 â€“ 9x = 2

E. 2y^2 â€“ 9x = 2
• 5.

### Evaluate the function at the specified value of the independent variable and simplify. Â

• A.

â€“14

• B.

0

• C.

3

• D.

-11

• E.

Undefined

E. Undefined
Explanation
In the given question, it is stated to evaluate the function at a specified value of the independent variable. However, the function is not provided in the question. Without knowing the function, we cannot determine its value at any specific value of the independent variable. Therefore, the answer is undefined.

• C.

-53

• D.

• E.

Undefined

B. 22
Explanation
The function is evaluated at the specified value of the independent variable, which is 22. This means that the function is substituted with the value 22 for the independent variable. The result of this substitution is the answer, which is 22.

â€“2 â‰¤ s â‰¤ 2

• B.

s â‰¤ â€“2 or s â‰¥ 2

• C.

s â‰¥ 0

• D.

s â‰¤ 2

• E.

All real numbers, except s=2, s=-2

A. â€“2 â‰¤ s â‰¤ 2
• 9.

### Which of the following graphs below does NOT represent y as a function of x?

• A.

A

• B.

B

• C.

C

• D.

D

• E.

All of the choices (A, B, C, & D) represent functions.

B. B
Explanation
Graph B does not represent y as a function of x because it fails the vertical line test. The vertical line test states that if a vertical line intersects a graph in more than one point, then the graph does not represent a function. In Graph B, there are two points where a vertical line intersects the graph, indicating that there are two different y-values for the same x-value, violating the definition of a function.
