Question

Determine the axis of symmetry for the function f(x)=3(x+4)^2 -6

Answer 1

x = -4

Explanation:

Answer 2

x = -4

Explanation:

To determine the axis of symmetry, we need to find the vertex point.

Since the equation is already in vertex form, we can easily tell that the vertext point is (-4,-6)

We know the axis of symmetry is going to be vertical, and vertical lines are in the form of "x = ...".

Since we know x value of the vertex is -4, we know the line of symmetry will be x = -4
