Question

using the graph, determine the equation of the axis of symmetry. answer attempt 1 out of 2

Explanation:

Step1: Identify vertex x - coordinate

The axis of symmetry of a parabola passes through its vertex. For a parabola opening upwards or downwards, the equation of the axis of symmetry is $x = h$, where $(h,k)$ is the vertex of the parabola. From the graph, the vertex of the parabola has an x - coordinate of - 4.

Answer:

$x=-4$
