Find the vertical asymptotes of the following function:
f(x)={x-3}/{(x-3)(x^2-4)}.

The equation(s) of the vertical asymptote(s) of f is/are___ & ____

asked by Jessica
  1. for vertical asymptote you are looking for those values of x which make the denominator zero, that is, that causes a division by zero

    so it must be
    x = 3 , x = 2, x = -2

  2. I have that the asymptotes are -2 and 2 however for my homework I need to write an equation to find the asymptote which I do not understand...?

  3. I wrote them as equations.
    x = 3
    x = 2
    x = -2

  4. I wrote it like that but the message that keeps popping up is "Unexpected character '='"
    I'm using WeBWorK if that is any explanation to why I'm having issues

  5. The flaw appears to be in the way WeBWorK accepts answers.
    If it asks for the "equation" of the asymptotes, then it should accept the = sign.
    try just inputting in 2, -2, and 3
