Question

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

(-2, -4)

(-2, 4)

(2, -4)

(2, 4)

Answer 1

f(x)= (x+2) ^3-4

Answer 2

That is the equation of a parabola.
The parabola's turning point is the vertex.
You find the vertex and you found the turning point.

Answer 3

the vertex form is a(x-h)^2+k ... how do I go from the parabola, to that?

Answer 4

By using vertex, the point should be (h,k) I think. If not, you can use dy/dx and equate it to 0
