Question

look at this graph: what is the equation of the axis of symmetry?

Explanation:

Step1: Identify the graph type

The graph is a parabola.

Step2: Recall axis - of - symmetry property

For a parabola symmetric about the y - axis, the equation of the axis of symmetry is $x = 0$. Since this parabola is symmetric about the y - axis.

Answer:

$x = 0$
