Find the equations of the vertical asymptote(s) of y ϭ Solution The solutions are x ϭ 1 and x ϭ Ϫ1. Since neither of these values makes the numerator zero, both x ϭ 1 and x ϭ Ϫ1 are equations of vertical asymptotes. Zeros The zeros, or roots, of a function f(x) are the x-values such that f(x) ϭ 0. Some zeros are found by factoring. Other zeros may be approximated on a calculator. In some cases, such as complex roots, the roots do not appear on the calculator, but can sometimes be found by algebraic methods.

The domain of a function is the set of its x-coordinates. The x-coordinate is called the independent variable. Often the easiest way to find the domain of a function is to locate the values of x for which the function is not defined. In a rational function, for example, the function is not defined at those values of x for which the denominator is zero. The domain of a function is the set of x-values excluding those for which the 22 Chapter 2 • Functions and Their Properties function is not defined.
