A function f(x) is said to have a jump discontinuity at x = a if: 1. lim f(x) exists. xa 2. lim f(x) exists. xa 3. The left and right limits are not equal. Let f(x) = 5x7, if x < 2 1 if x 2 x + 9' Show that f(x) has a jump discontinuity at x = 2 by calculating the limits from the left and right at x = 2. lim f(x) x 2 lim f(x) I 2+ Now for fun, try to graph f(x).
