What are the coordinates of the vertex?
-
(4, -3)
-
(3, -4)
-
(2, 4)
-
(4, 2)
-
(4, -2)
Correct Answer
A. (3, -4)Explanation
The coordinates of the vertex can be determined by finding the midpoint between the x-coordinates and the y-coordinates of the given points. In this case, the midpoint between 4 and 2 is 3, and the midpoint between -3 and -2 is -4. Therefore, the coordinates of the vertex are (3, -4).Rate this question:

Does the parabola open up or down?
- 4.
The y-intercept is (0, _____).
Correct Answer
(0, 4)Explanation
The y-intercept is the point where a line or curve intersects the y-axis. In this case, the y-intercept is given as (0, 4), which means that the line or curve crosses the y-axis at the point (0, 4). This means that when x is 0, the corresponding y value is 4.Rate this question:
