Question

The axis of symmetry for the function f(x) = −x2 − 10x + 16 is x = −5. What are the coordinates of the vertex of the graph?

(−5, 41)
(−5, 56)
(−5, 76)
(−5, 91)

Answer 1

the graph of f(x)= -2-10x+16

Answer 2

the vertex would be (-5,41)

Explanation:

You just plug the -5 back into the equation to get 41
