Show that f(z) is always decreasing over (0, 00). Part B. Use limits and the fact that f(x) is continuous on (0,oo) (you don't have to prove continuity although see Part D below) to find the largest and smallest values that f(x) takes on, or to show that there is no largest (and/or no smallest) value of f(a). Use those values to say what range of values f(z) takes on over the interval (0, oo). Hint: what does the fact that f(x) is continu occur? ous and always decreasing tell you about where the largest and smallest values must Part C. U se Mathematica or similar technology to graph f(x) over a large enough part of the interval (0, oo) to visually check that your answer to Part B is plausible. Part D. For up to 2 points of extra credit, prove that f(x) really is continuous on the interval (0,00). Question 4. (Based on OpenStax Calculus, Volume 1, Problem 341 in Section 4.7.)

takes on over the interval (0, 0o). Answer my curiosity in the following steps...
Part A. Show that f(z) is always decreasing over (0, 00).
Part B. Use limits and the fact that f(x) is continuous on (0,oo) (you don't have to prove continuity
