Question

What are the coordinates of the vertex in f(x) = -4(x+3)^2-8

Answer 1

Answer:

vertex = (- 3, - 8 )

Step-by-step explanation:

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) = - 4(x + 3)² - 8 ← is in vertex form

with (h, k) = (- 3, - 8 ) ← vertex
