A friend has taken a function f(x) and applied the graphing strategy from today's lesson and obtained the following information. Give a sketch of any function y = f(x) for which all of the below information is true.
- The domain of f(x) is (0,10)(10,).
- The function f(x) has x-intercepts at x = 3 and x = 5, but no y-intercepts.
- The function f(x) has a vertical asymptote, x = 0, and a horizontal asymptote, y = 0.
- The critical numbers of f are x = 4,7,9.
- The function f(x) is increasing on the intervals (0,4), (9,10), and (10,).
- The function f(x) is decreasing on the intervals (4,7), (7,9).
- The function f(x) has a local maximum at x = 7 and a local minimum at x = 9.
- The function f(x) is concave up on the subintervals (6,7) and (8,10).
- The function f(x) is concave down on the subintervals (0,6), (7,8), and (10,).
- The function f(x) has inflection points at x = 6,7,8 (at x = 10 the definition of an inflection point does not apply because x = 10 is not in the domain of f).
