Question

How do you find the equation of a parabola with zero's (-3,0) and (4,0)?

Answer 1

kinda work backward from the steps you would take to solve for the zeros...

if x=-3 is a zero then

x+3 could be a factor because x+3=0------>x=-3

same for the next one, x-4=0

so multiply together to get the equation

y=(x-4)(x+3)
