    \[f(x)=2x\]\[g(x)=x^2+2\]\[f(g[x]) = 2(x^2+2)\]

    because you "put" g(x) inside f(x)

    So this question is actually two separate questions one to find the (fog) and (gof) but have the same multiple choices which are: A. 2x^2+4 B. 4x^2 +2 C. -8x+6 D. -4x^2-5 My guesses for (Gof) is B (Fog) is A Is this correct?
