480700. The different combinations of students that could go on the trip with a total of 25 student, but only 18 may go, is 480700.
The key to solve this problem is using the combination formula
. This mean the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed.
The total of students is n and the only that 18 students may go is r:

According to the question, to express the rational function for the vertical asymptote whose equation is
and horizontal asymptote whose equation is at 
As per the question, the function 'f(x)' is vertical at
. Therefore, the denominator be 

The function 'g(x)' should have same degree as the denominator function has and it is defined as
The rational function can be written as:
Rational function = 
What is rational function?
