Question

What is the equation of the axis of symmetry for the parabola y=-1/2(x+3)^2-5

Answer 1

x = -3

Explanation:

Answer 2

Now remember that the vertex's x-coordinate is the same as the axis of symmetry. In this case, looking at the vertex form equation, the vertex's x-coordinate is -3, therefore the equation for the axis of symmetry is x = -3.
