Yes, but going from there, I don't know how to find the x. It's just too confusing from there. I don't know which exponent I can factor out.

Plato is correct. If you want f of g, you just plug the g function into the x spot on the f function.

Does this make sense?

If I am incorrect on this please correct me!:) - Oct 9th 2012, 11:40 AMPlatoRe: Formula for f of g
