In Exercises 19-21. sketch the graph of the rational function. As sketching aids, check for intercepts, vertical asymptotes, horizontal asymptotes, and slant asymptotes. 20. g(x) = - r+2 19. h() = 21. /r) = 20- + 9 X - 1 5x3 + 2 Defense budget, A 22. The table shows the amounts A (in billions of dollars) budgeted for national defense Year (in billions for the years 1998 to 2004. (Source: U.S. Office of Management and Budget) of dollars) (a) Use a graphing utility to create a scatter plot of the data. Let / represent the year. 1998 271.3 with / = 8 corresponding to 1998. 1999 292.3 (b) Use the regression feature of a graphing utility to find a quadratic model for the 2000 304.1 data. 2001 335.5 (c) Use a graphing utility to graph the quadratic model with the scatter plot from part (a). Is the quadratic model a good fit for the data? 2002 362.1 (d) Use the model to estimate the amounts budgeted for the years 2005 and 2010. 2003 456.2 (e) Do you believe the model is useful for predicting the national defense budgets for 2004 490.6 years beyond 20047 Explain. Table for 22In Exercises 8 and 9, list all the possible rational zeros of the function. Use a graph- ing utility to graph the function and find all the rational zeros. 8. g() = 2/4 - 313 + 161 - 24 9. h(x) = 3x3 + 2+4 - 3x - 2 10 Find all the zeros of the function /(x) = > - 7x- + Ilx + 19 and write the polynomial as the product of linear factors
