Question

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

Explanation:

Step1: Identify x-intercepts

The parabola crosses the x-axis at $x=0$ and $x=8$.

Step2: Calculate midpoint of intercepts

The axis of symmetry is the midpoint of the two x-intercepts.
$\text{Midpoint} = \frac{0 + 8}{2} = 4$

Answer:

$x=4$
