A function f(x) is said to have a jump discontinuity at x = a if: 1. lim f(x) exists. 2. lim f(x) exists. 3. The left and right limits are not equal. 6x - 7, if x 7 Show that f(x) has a jump discontinuity at x = 7 by calculating the limits from the left and right at x = 7. lim f(x) lim f(x) 20 - 7+ Now, for fun, try to graph f(x).Find the values of c and d that make the function 3x if x 2 continuous. C = d =What values of a and b make the function f continuous everywhere? 4 if x 3 a and b
