If f(x) = x^2 and g(x) = 2x + 1, WHICH EXPRESSION IS EQUIVALENT TO (F O G)(X),

(2x+1)^2 or 4x^2+4x+1

Step-by-step explanation:

I'm going to assume you need to find f(g(x)) when f(x)=x^2 and g(x)=2x+1

You first need to find g(x) which is 2x+1

You then take the f(x) function and replace x with 2x+1

This means our new equation is

(2x+1)^2

Your teacher may or may not want you stop here, really only you know the answer to that

But if we expand this we'll find that (2x+1)^2=4x^2+4x+1
