Question

using the graph, determine the equation of the axis of symmetry.

Explanation:

Step1: Identify symmetry property

The axis of symmetry of a parabola passes through its vertex.

Step2: Locate vertex on graph

The vertex of the parabola in the graph is at the point $(-3,-1)$.

Step3: Write axis - of - symmetry equation

For a vertical parabola, the equation of the axis of symmetry is $x =$ the x - coordinate of the vertex. So the equation is $x=-3$.

Answer:

$x = - 3$
