  Solution
18 ) Graph has x intercepts at x=-1 and x =3
So, numerator = (x+1)(x-3) = x^2 -2x -3
So, Option C
19 ) y = (x^2 -2x-3)/(3x -3)
Vertical asymtote : 3x -3 = 0 ---> x = 1
20) The graph is neither even nor odd
21) The end behaviour of y = (x^2 -2x-3)/(3x -3) can be found using long division
y = x/3 -1/3 - 4/(3x -3)
there is an oblique asymptote at y= x/3 -1/3
So, end behaviour is y = x/3 -1/3
22) The function has vertical asymtotes at x= -3 and x=3
Denominator of function : x^2 -9
Option A : y = 2x^2/(x^2 -9)
25) The end behaviour behaves as: y =2x^2/x^2 = 2 as x---> infinity
y = 2
