Question

What are the coordinates the vertex for the quadratic function below? f(x)=-5(x-10)^2-8

Answer 1

Answer:

  D)  (10,-8)

Step-by-step explanation:

The vertex form of the equation of a parabola is ...

  f(x) = a(x -h)^2 +k . . . . . . for vertex (h, k) and scale factor "a"

Matching this pattern to the given equation, we see that ...

  a = -5, h = 10, k = -8

so the vertex is (h, k) = (10, -8) . . . . . matches choice D
