4(x^22x+1)+1=f(g(x)) 4x^28x+4+1=f(g(x)) f(g(x))=4x^28x+5

Sub g(x) into wherever x is inside f(x)

let's call g(x) something you are more familiar with, like g(x) = y, then sub that into f(g(x)) Which gives you f(y)=4x+1

Since you substitute whatever is inside f() into any x you have in your function, you'll get 4(y)+1=f(y) Then just resub y=g(x) = x^2 – 2x + 1
