Question

If f(x)=2x+1 and g(x)= 3x+1, then f(g(x))= ?

Please show your work when answering! Thank-you!

Answer 1

Well, first we have to plug in g(x) into f(x). This gets us f(g(x)) = 2(3x + 1) + 1. Then, we simply distribute and add the 1. This gets us an answer of f(g(x)) = 6x + 3.

Hope this helps!
