I would like to check my work:

Problem

Iff(x)=[a][b]x+x^2andg(x)=x/x[c]+1.5, findf(g([d]))andg(f([d]))by first determiningf(g(x))andg(f(x))before evaluating for[d]. Round the answers to two decimal places.

F(x) = 8 - 2x + x^2

G(x) = x/x-[3] +1.5

G = x/ x- 1.5

F(g (3)) = 8-2x + 3x^3/ x-1.5

G (f(3)) = 8x -2x^2 + 3x^3/x - 1.5

???
