question

The graph shows a parabola. What is the equation of its axis of symmetry?

key idea

The axis of symmetry is the line that divides a parabola into two parts that are mirror images. If the parabola opens up or down, the axis of symmetry is vertical. If the parabola opens right or left, the axis of symmetry is horizontal. For example:

The vertex is the point where the axis of symmetry intersects the parabola.

solution

Look at the graph of the parabola:

The axis of symmetry is the

-axis,
