If f(x)= 4x^2 and g(x)= x+1, find (f * g)(x). a. 4x^3 + 4x^2 b. 4(x+1)^2 c. 4x(x) d. 4x^2+1

The answer is b. the outside function is f(x) and the inside function is g(x). this means that you will use f(x) to start with. when you come across an ‘x’ in the function, you will insert g(x) in place of it and continue along.
