b. Which function represents the revenue function?

c. How can the functions be combined to create profit function?

d. Write the profit function.

## Answers ( No )

A. It is given that the first one is the cost. Therefore, f(x)=100+3x.

B. g(x)=8x is the revenue because it is said to be one.

C. You can use f composition of g. This basically means that you can combine the system.

D. Whenever there is x replace it with the other function

f(g(x))= 100+3(8x)

f(g(x))= 100 + 24x
