The function m) : 762:3 + 45:32 + 2523 + 8 is increasing on the interval ( D , D ). It is decreasing on the interval ( 00, C] ) and the interval (D, 00 ). The function has a local maximum at m. Which of the following ensures that a function f is continuous at -9? (a) Hat f(?) exists. 3479 (b) 1179) exists. (c) Jim fix) = f(9)- 2&7!) (d)A|| of the above. (e) None of the above. Answer: D Given 59GB) : 21/3 :3, show the function is continuous at :1: : 2 by computing (a) 9(2) and 020135 9(3)- (3 (b
