Answer:
A. 
B. 
C. 
D. 
Step-by-step explanation:
A. To solve the first part of the problem we must replace
in the function 
So:

B. In part B we must find the inverse function of 
To find the inverse function do 

Now clear the variable x.

Replace x with y.

Finally

C. Now we take the inverse function found above and replace 

D. Now we substitute
in the original function.

Answer:
absolute value function
Step-by-step explanation:
By substitution.
Get y or x alone then insert it into the other equation solving for one of the two variables. After that substitute ur answer into one of the equations then solve.
