Answer: True
One example would be f(x) = 3/(x-2). Here the 'a' value is a = 2.
Plugging x = 2 into f(x) leads to a division by zero error. Visually the graph will have a vertical asymptote through 2 on the x axis. The vertical asymptote is like an electric fence in which the graph slowly approaches but never touches or crosses.
