Hello from MrBillDoesMath!

Answer:  Choice D,  3 (x^2+1) + 2

Discussion:

f(g(x)) = f (x^2 + 1)     * Note: I think that "x2" was meant to be x^2

         = 3 * (x^2 +1) + 2 =

         (3 x^2 + 3) + 2                  

Factor 3 from each term:

         = 3 (x^2 _1) + 2


which is choice "d".


Thank you,

MrB
