To write the equation of a parabola in the form $y = a(x - p)(x - q)$, we need to identify the following components from the graph:

1. The x-intercepts (roots): These are the points where the parabola crosses the x-axis. These values will correspond to $p$ and $q$.
2. The coefficient $a$: This controls the direction and width of the parabola. If the parabola opens upward, $a$ will be positive, and if it opens downward, $a$ will be negative.

Please upload the graph of the parabola so I can help you identify these components and write the equation.
