Question

The image of a parabolic lens is projected onto a graph. The image crosses the x-axis at –2 and 3. The point (–1, 2) is also on the parabola. Which equation can be used to model the image of the lens?

y = (x – 2)(x + 3)
y = (x – 2)(x + 3)
y = (x + 2)(x – 3)
y = (x + 2)(x – 3)

Step-by-step explanation:

Given

— a point on the parabola

Required

The equation

First, calculate the equation from the zeros

Substitute and

To solve for k, we substitute

Divide by -4

So, the equation is:
