Question

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

Answer 1

(-5,41)

Explanation:

The axis of symmetry is the x coordinate for the vertex. so, x= -5. Now plug that into the equation:

-(-5)^2 - 10(-5) + 16 ***I'm assuming it is 10x though it says just 10

-25+50+16= 41

The vertex is at (-5,41)
