Question
(e) none o e 7. The graph of the function /(x) is shown below. The domain of f(x) is the interval (0,3]. Select all correct statements. f(x) (i) f(z) attains its global maximum at z = 1. (ii) f(x) attains its global minimum at 1 (iii) f(x) attains a local maximum at 2 (iv) f(x) attains its global minimum at x = 3. (a) (1) and (iii); (b) (ii) and (iv); (e) (ii) and (i); (d) (i) and (iv). 8. Let f(z) be a continuous function on the interval [a, b. Suppose f(x) has no critical numbers on la, bi. Which statement is correct? (a) f(z) has no global extrema on [a, b. (b) f(z) attains its global extrema on la, b] inside of the interval (a,b). (c) f(x) attains its global extrema on [a,b] at the endpoints x a and x=b. (d) Nothing can be said about the global extrema of f(x) on la,b), 9. Let f(x) be a function continuous everywhere. Suppose f() exists for every value of r and its signs on the real line are given below.Explanation / Answer
