Question

If f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to f(g(x))?

Answer 1

Answer:

3(x^2+1)+2

Step-by-step explanation:

since g(x) is equal to x^2+1 you can substitute x^2+1 for g(x) which will be f(x^2+1). then you can substitute f(x) for 3x+2 and in the end you will get 3(x^2+1)+2
