If I have a function:
f(x) = 4(x^3) + 150(x^2) + (-126)(x) + 446

how would I solve for x if f(x)=448 ?

If it's easier to explain you can just use a generic equation:

f(x) =A(x^3) + B(x^2) + C(x) + D

as long as F(x)!=0.

Thanks,
Matt

hi
see http://www.1728.com/cubic2.htm for the solution to cubic equations - just punch your numbers in and follow the trail!

Hopefully, you'll get one answer that makes sense in the context you're using it.
