9. Find (f. g)(a) if f(a) = . and g(a) = 2². Fully simplify your answer. A. (F•g) = 1/a

B. (F•g) (a) = a

C. (F•g) (a) = 1/a^2

D. (F•g) = 1

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Your answer should be 1/3. i hope i could ! good luck : )
