A function of x means that you get an answer if you plug in a certain value for x.

A is not a function, because it specifies that x=5
B could be a function, but you'd have to rewrite it in a form y = ....
C is a nice function of x. Just swap it: y=x2
D is a circle. You can't rewrite it as a clean function of x. 

So I would choose C.

Answer:

3 years 8 month

Step-by-step explanation:

Given 7 years 6 months - 3 years 10 months

Step 1: Firstly we should subtract months from months then after from year to year.

Step 2: 6 months is less than 10 months so we have to borrow 1 year and add it to the months.

Step 3: Adding 1 year to 6 months we get 18 months.

Step 4: Now we have to subtract 3 years 10 months from 6 years 18 months.

6\ years\ 18\ months-3\ years\ 10\ months=3\ years\ 8\ months

Step 5: After subtracting we get 3 years 8 months.

Thus the answer is 3 years 8 months.
