A parabola has a vertex at (-3,2).
Where is the axis of symmetry?

• y = -2

• x = 3

• x = -3

• y = 2

The axis of symmetry for a vertical parabola always matches...

• the y-intercept

• the y-value of the vertex

• the x-value of the vertex

• the x-intercepts

Find the vertex, AOS, and y-intercept for the following equation.
