Answer 1

First find g(x)

Answer 2

how do i do that do i just plug in f(x)

Answer 3

Can u find f(1)

Answer 4

f(1)=7

Answer 5

Does radical means square root? here

Answer 6

Just know that (f+g)(1)=f(1)+f(g)

Answer 7

but what do i do to solve for f(X) if theres only giving me sets of numbers
