Answer:
Given the graph
and 
We have to find the value of k;
Since, g(x) = f(x) +k

Subtract
from both sides we get;

Add 2 to both sides we get;

Simplify:

or
k = 5
Therefore, the value of k = 5
So, what you would have to do is figure out how old he is not which is 30 yrs old because it is half of 60.
So, after this you would have to find a number that would go into 60 four times which is 15.
So, your answer would be 15.
