Question: (1 point) A function f () is said to have a jump discontinuity at a = a if all three of the following conditions hold:

(1 point) A function f () is said to have a jump discontinuity at a = a if all three of the following conditions hold: 1. lim f(ac) exists. 2. lim f(a) exists. 3. The left and right limits are not equal. Show that x + 4x +4 ifx 4 has a jump discontinuity at x = 4 by calculating the limit as a approaches 4 from the left and from the right. lim f(x) = lim f(x) = Now draw a graph of f (x)
