cubic polynomials
ok so I feel really stupid right now cause I can't figure this out:
The graph of a cubic polynomial function has xintercepts 3,1,and 2. The graph also passes through the point A(1,24)
Determine the function in the factored form a(xr1)(xr2)(xr3) where r1 ect represents the roots algebraically
Umm How do you solve for the a value? I know its vertical strech but can't figure it out.
Oh and I know a=3 but I can't do it algebraically


Thanks, (Happy)
I can't belive it was that simple!
