For the following exercises, for each pair of functions, find a. 






(fg)
(x)

(fg)(x)

and b. (gf)(x)

(gf)(x)

Simplify the results. Find the domain of each of the results.

42

f(x)=3x,g(x)=x+5

f(x)=3x,g(x)=x+5 

43

f(x)=x+4,g(x)=4x1

f(x)=x+4,g(x)=4x1 

44

f(x)=2x+4,g(x)=x22

f(x)=2x+4,g(x)=x22 

45

f(x)=x2+7,g(x)=x23

f(x)=x2+7,g(x)=x23 

46

f(x)=x−−√,g(x)=x+9

f(x)=x,g(x)=x+9 

47

f(x)=32x+1,g(x)=2x

f(x)=32x+1,g(x)=2x 

48

f(x)=|x+1|,g(x)=x2+x4

y=f(x),y=f(x),
