1.   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 = 0. B. There is a vertical asymptote at x = a.
    C. There is a point discontinuity. D. f(a) = 0
    Hint

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

  3.   Write the equation(s) of the vertical asymptote(s) of the function.
    A. x = 3, x = –5 B. x = –5
    C. x = 3 D. x = –3, x = –5
    Hint

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

  5.   What is the equation of the vertical asymptote in the figure?
