Problem 4. (1 point) Problem 6. (1 point) A function f(x) is said to have a jump discontinuity at x = a if: Let 1. lim f(x) exists. -6x, x 6. Find the indicated one-sided limits of f, and determine the conti- nuity of f at the indicated point. 5x -2, ifx 2 C ) True in some cases; False in others. Show that f (x) has a jump discontinuity at x = 2 by calculating the limits from the left and right at x = 2. 1. f(0) = 0 lim f (x) = Answer: (A, B, or C ) 1-+ 2- lim f (x) = x-+2+ 2.
