Determine the axis of symmetry for the function f(x) = 5(x + 1)2 − 8.
x = −8
x = 8
x = −1
x = 1

C.

Step-by-step explanation:

We have been given a function formula . We are asked to find the axis of symmetry for the given function.

We can see that our given function is a parabola in vertex form. We know that vertex from of parabola is , where (h,k) represents vertex of parabola.

Let us convert our given function in vertex form as:

We know that axis of symmetry of a parabola is the equation of x-coordinate of vertex, which in form .

Since the x-coordinate of vertex is , therefore, the axis of symmetry for the given function would be .
