Determine the axis of symmetry for the function f (x) = - 2 (x + 3) 2 - 5.

Ox=3

Ox=-3

Ox=5

Ox=-5

x=-3

Step-by-step explanation:

f (x) = - 2 (x + 3) ^2 - 5

This quadratic is in the form

f (x) = a (x - h) ^2 + k

f (x) = - 2 (x - - 3) ^2 + - 5

Where (h, k) is the vertex

(-3,-5)

We know the axis of symmetry is along the vertex

x=h is the axis of symmetry

x=-3
