Question

What are the coordinates of the turning point for the function f(x) = (x + 2)3 − 4?

Answer 1

Answer:A

Step-by-step explanation:

Given

$F(x)=(x+2)^3-4$

Turning Point is the point where the graph changes its nature i.e. either increasing to decreasing or decreasing to increasing

to find turning point

$F'(x)=3(x+2)^2+0$

For critical point

F'(x)=0

$3(x+2)^2=0$

x+2=0

x=-2

$F(x)=(-2+2)^3-4=-4$

thus

(-2,-4 ) is the turning Point where Function changes its nature
