a) you plug in g(x) in place of each x in f(x). So you do 9(9x)+4 = 81x+4, domain is all real numbers.

b) you plug in f(x) in place of each x in g(x). So you do 9(9x+4) = 81x+36, domain is all real numbers

c) you plug in f(x) in place of each x in f(x). So you do 9(9x+4)+4= 81x+36+4 = 81x+40, domain is all real numbers.

d) you plug in g(x) in place of each x in g(x). So you do 9(9x) = 81x, domain is all real numbers.
