The rational function f is defined as, where h and g are polynomials.
 The degree of h is m and the degree of g is n.
 Which of the following statements are TRUE?
 I. If m > n the absolute value of the function approaches positive infinity as x gets very large.
 II. If m < n the value of the function approaches zero as x gets very large.
 III. If m = n the value of the function approaches a constant as x gets very large.
