Question

Which describes the graph of y=-(x+5)^2+3

Answer 1

Maximum at (-5, 3)
Y’ = -2(x+5)
=> maximum when y’ = 0

Answer 2

Maximum at (-5, 3)

Explanation:

The quadratic equation is in vertex form, which specifically shows the vertex.

Since the a is negative, you get a maximum y value of 3.

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