8-48.

Write a polynomial equation for a graph that passes through the point (–1, 60) and has three *x*-intercepts: (–4, 0), (1, 0), and (3, 0). Homework Help ✎

Start by writing an equation in factored form.*p*(*x*) = *a*(*x* + 4)(*x* − 1)(*x* − 3)

Find the stretch factor by substituting the point.
