    A. y = 1 B. x = 2
    C. x = 1 D. x = -4
    Hint

  2.   If the rational expression of a function in simplest form is defined for x = a, but the original function is undefined for x = a, what happens at x = a?
    A. There is a vertical asymptote at x = a. B. There is a point discontinuity.
    C. f(a) = 0 D. There is a vertical asymptote at x = 0.
    Hint

  3.   What is the equation of the vertical asymptote of the function ?
    A. x = 4 B. x = –4
    C. x = 5 D. There is a hole at 4, not a vertical asymptote.
    Hint

  4.   The function has which of the following properties?
    A. f(x) = 1 for all values of x. B. It has a hole at (3, 1).
    C. f(x) = 0 for all values of x. D. It has a hole at (3, 0).
    Hint
