The graph below represents a rational function y fx a State
     The graph below represents a rational function y = f(x).  (a) State the vertical asymptote.  (b) State the horizontal asymptote.  (c) The graph represents which of the following functions?  Choice ___  f(x) = 5x^2/x^2-9  f(x) = 5x/x-3  f(x) = 3x/x-5  f(x) = 5/x-3  The graph below represents a polynomial function y = f(x).  (a) Is the degree of the polynomial odd or even?  (b) State the interval(s) on which the function is increasing.  (c) State the value of f(-2). 
  
  Solution
Q7)
a) Vertical asymptote: x = 3
b) Horizontal asymptote: y = 5
c) f(x) = 5x/(x-3)
Option B is correct
Q8) a) Odd because it has three roots
b) (-4,1)
c) f(-2) = 0
