Answer:
it is not always possible to find their intersection point for e.g take 
y=x-1 it's inverse is y=x+1 so their is no intersection point but generally u find intersection points by equalizing their functions 
f(x)=f^-1(x)
 
        
             
        
        
        
Her credits need to be AT LEAST EQUAL TO OR GREATER THAN 144 (credit hours) so we can eliminate choices B and D. 
She already completed 4 semesters in which she receives 15 credit per semester. 
This expression can be written as 4(15). 
She needs to do a certain remaining hours of credit which can be represented by c and only c without any other coefficient. 
So, the most reasonable choice here is A.
