Question

are the coordinates of the vertex of the parabola described by the equation below?

y = –5(x + 2)2 + 7

A. (–2, 7)
B. (2, –7)
C. (–7, –2)
D. (7, 2)

Answer 1

I think it's b

Answer 2

Compare:

y = a(x - h)^2 + k

with the given equation:

h = -2
k = 7

so the vertexd = (h, k ) = (-2, 7)
