1 Section Rational Functions and Inequalities A rational function is a quotient of two polynomials. That is, is a rational function if =, where and are polynomials and is not the zero polynomial. The domain of the rational function =/ is the set of all -values for which 0. (The zeros of the denominator are excluded from the domain.) Example Find the domain and the - and -intercepts of the graph: =
2 Example Find the domain and sketch the graph: = Asymptotes... The line = is a vertical asymptote of the graph of the function if ± as. (This says that increases without bound as approaches.) The zeros of the denominator of a rational function give possible vertical asymptotes... The rational function =/ has a vertical asymptote at = if =0 and 0. If =0 and =0, simplify the rational expression first and then check again for the zeros of.
3 Examples Determine all vertical asymptotes. 1. = = h= 9 +3
4 The line =# is a horizontal asymptote of the graph of the function if # as or # as. While the graph of a rational function can have any number of vertical asymptotes, it can have at most one horizontal asymptote. VERY IMPORTANT IDEA: Horizontal asymptotes can be found by examining the degrees of the numerator and denominator polynomials. 1. If the degrees are equal, the horizontal asymptote is = # $, where and # are the leading coefficients of the numerator and denominator, respectively. 2. If the degree of the denominator is greater than the degree of the numerator, =0 is the horizontal asymptote. 3. If the degree of the numerator is greater than the degree of the denominator, the graph has no horizontal asymptote.
5 Examples Determine whether the graph of the rational function has a horizontal asymptote. If so, find an equation. 1. = = h= 7& & =
6 A non-horizontal or non-vertical line that a graph approaches as is called a slant (or oblique) asymptote. The graph of a rational function has a slant asymptote if the degree of the numerator is exactly one more than the degree of the denominator. To determine an equation for the slant asymptote, carry out long division: after long division, if the quotient is "#, then "# is an equation of the slant asymptote. Example Let = Use your calculator to graph the function and then use long division to find an equation of the slant asymptote. Long division gives " 5"7. Therefore the slant asymptote 4 has equation.
7 Graphing rational functions... To graph the rational function : 1. Completely factor the denominator and specify all real numbers excluded from the domain of. 2. Completely factor the numerator and cancel any factors common to both the numerator and the denominator. (If any factors cancel, your graph will have holes at the corresponding -values.) 3. Examine the factors that remain in the denominator. Then find and sketch the vertical asymptotes. (Sketch with a dashed line.) 4. Find and sketch (dashed) any horizontal or slant asymptotes. 5. Determine the - and -intercepts of the graph. 6. Construct a sign chart: Away from your graph, sketch a number line separated (in order) by the -values associated with the vertical asymptotes, -intercepts, and other points excluded from the domain. Mark which is which. Then determine and mark the signs (" or ) of on each interval of your number line. 7. Plot some points. 8. Determine if there is symmetry in the graph. 9. Use all the information above to sketch the graph. Use your graphing calculator as an aid.
8 Examples
9 Rational inequalities... To solve a rational inequality: 1. Use algebra to get a single rational function,, on one side of the inequality and a zero on the other side. 2. Follow the steps for graphing up through step 6 where you construct the sign chart. 3. Use you sign chart to solve the inequality. Pay close attention to whether zeros should be included or excluded from your solution. 4. Write your final answer in interval notation. Examples
