look at the denominator. What happens to a function which has a zero in the denominator?

consider y = 1/x
division by zero is not defined. The closer x gets to 0, the larger y gets. At x=0, y is undefined, infinitely large.
Same for this problem. What happens to y as x gets close to 2? x^2-4 gets close to 0, and you cannot divide by 0.
