Precal rational

In Exercises 27-36, use a graphing utility to graph the function. Determine its domain and identify any vertical or horizontal asymptotes. 27. f(x) = 2+ x 28. /(x) = 3 - x 1 - x 2 - x 29. /(1) = 31 + 1 30. A(x) = - 2 31. h(i) = 12 + 1 32. g(x) = (x - 2)2 33. f(x) = - x+1 34. /(x) = - x1 -x-6 x'+x-6 In Exercises 9-26, sketch the graph of the rational function 35. f(x) = - 20x by hand. As sketching aids, check for intercepts, vertical x3 + 1 36. /(x) = 5-4 + + 2 asymptotes, horizontal asymptotes, and holes. Use a graphing utility to verify your graph. 9. f(x) = = x + 2 10. / (x) = = x - 6 16. g(x) = = 22. f (x) = 2x x' + x - 2 24. g(x)= 5(x + 4) x+x- 12 26. f(x) =* - 16 x - 4
