Answer: OPTION B
Step-by-step explanation:
 You can observe that the exercise provides you two Linear functions.
 The first Linear function is the function f(x). This is:
 
 And the other Linear function is the function g(x):
 
 In order to find  , you need to follow these steps shown below:
, you need to follow these steps shown below:
 <u>Step 1</u>: 
 You must substitute the function f(x) into the function g(x); this means that the function f(x) will be in the place of the variable "x" of the function g(x); as you can observe below:
 
 <u>Step 2</u>: 
 Finally you must combine the like terms (You can notice that the like terms are 1 and 14; then you must add them). Therefore, you get that   is:
 is:
