Which equation when graphed has x-intercepts at (8,0) and (-2, 0) and a y-intercept at (0-48)?

Step-by-step explanation:

we know that

The equation of a vertical parabola in factored form is equal to

where

a is a coefficient

x1 an x2 are the roots or x-intercepts

In this problem we have

substitute

with the y-intercept (0,-48) find the value of a

substitute

The equation is equal to
