Question

Find the vertex of the graph of the function.

f(x) = (x - 10)2 - 8

(10, -8)

(-8, 0)

(0, 10)

(-8, 10)

Answer 1

vertex = (10, - 8)

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = (x - 10)² - 8 is in this form with (h, k) = (10, - 8) ← vertex
