Question

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

Explanation:

Step1: Identify vertex x-coordinate

The axis of symmetry of a parabola is the vertical line through its vertex. From the graph, the vertex (lowest point) has an x-coordinate of 3.

Step2: Write axis equation

The equation of a vertical line is $x = a$, where $a$ is the x-coordinate of any point on the line. Here, $a = 3$. So the equation is $x = 3$.

Answer:

$x = 3$
