Question

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

Explanation:

Step1: Identify x-intercepts

The x-intercepts are $x=-1$ and $x=6$.

Step2: Calculate midpoint of intercepts

The axis of symmetry is the midpoint of the x-intercepts, calculated as $\frac{x_1 + x_2}{2}$.
$\frac{-1 + 6}{2} = \frac{5}{2} = 2.5$

Answer:

$x=2.5$ (or $x=\frac{5}{2}$)
