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
