Homework Statement
Find an expression for a cubic function f if f(1)=6 and f(-1)=f(0)=f(2)=0
Homework Equations
I figured it out but I am not sure why we use the equation f(x) = a[x-(-1)](x-0)(x-2)
The Attempt at a Solution
Im assuming its because if u times that equation that is a cubic function, but does it have anything todo with f(-1)=f(0)=f(2)=0 ?
