Answer:


Step-by-step explanation:
We know the definition of both functions:
, and 
A) In order to evaluate what
, let's first investigate what g(-1) is using the definition for this function:

Now let's find what f(2) is using f(x) definition: 
B) In order to evaluate what
, let's first investigate what f(3) is using the definition for this function:

Now let's find what g(7) is using the definition for this function:

Answer: 43/14
Step-by-step explanation: You take you 3 and times it by 14 and + 1 because the equation is saying 14/14 3 times plus the 1/14,
So 3 times 14=42
42+1=43 and then you take the 43 and put it over the 14 so now you have your answer: 43/14
