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
Ierofanga [76]

Answer:

y =-\frac{1}{2}(x +2)(x - 3)

Step-by-step explanation:

Given

x_1 = -2

x_2 = 3

(x,y) = (-1,2) --- a point on the parabola

Required

The equation

First, calculate the equation from the zeros

y =k(x - x_1)(x - x_2)

Substitute x_1 = -2 and x_2 = 3

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

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

To solve for k, we substitute (x,y) = (-1,2)

2 = k(-1+2)(-1-3)

2 = k(1)(-4)

2 = -4k

Divide by -4

k=\frac{2}{-4}

k=-\frac{1}{2}

So, the equation is:

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

y =-\frac{1}{2}(x +2)(x - 3)
