Problem 1
For functions like f(x), the input is x and the output is f(x). 
If x = 7, then f(7) = 12 has the input 7 and output 12. 
Therefore the ordered pair is (7, 12) which is the answer
=====================================================
Problem 2
Replace every x with 3 and simplify
f(x) = 3*x
f(3) = 3*3
f(3) = 9
The input x = 3 leads to the output y = 9. Recall that y = f(x).
So (3,9) is the answer here.
