Solution

The equation of a parabola in the form y = a(x - p)(x - q) that passes through the points (-2,0), (3,0), and (1,-48) can be found by setting up a system of equations using these points.

First, we know that the roots of the parabola are x = -2 and x = 3, because these are the x-values where y = 0. So, we can write the equation as:

y = a(x - (-2))(x - 3)

or

y = a(x + 2)(x - 3)

Next, we can use the third point (1,-48) to find the value of a. Substituting x = 1 and y = -48 into the equation gives:

-48 = a(1 + 2)(1 - 3)

or

-48 = a(3)(-2)

or

-48 = -6a

Solving for a gives a = 8.

So, the equation of the parabola is y = 8(x + 2)(x - 3).
