Question

The vertex of this parabola is at (-5, 4). Which of the following could be its

equation?
(-5, 4)

A. y* -(x + 5)2 - 4
B. y = -(x - 5)2 - 4
C. y = -(x - 5)2 + 4
D. y = -(x + 5)2 + 4

Answer 1

D

Explanation:

Because the x-coordinate of the vertex is negative, only A or D could be the correct equation for this parabola. D is correct because its constant (4) matches the y-coordinate of the vertex (-5, 4).
