# Composite Functions Help

1. two functions are defined as f(x)=x^2 and g(x)=x^2+4x-1, find a and b so that g(x)=f(x+a)+b

Just need a little help with this question as I am not too sure where to start etc. I have recognized that it wants it in a 'complete the square form' but that's about it!! Thanks in advance!

Compute f(x+a) + b in terms of x, a, and b and you'll see it from there.
