A function f(x) is said to have a jump discontinuity at x=a if: 1. limx→a− f(x) exists.

2. limx→a+ f(x) exists.

3. The left and right limits are not equal.

Let f(x)= {3x-3 if x <10

{4/x+4 if x ≥ 10

Show that f(x) has a jump discontinuity at x=10 by calculating the limits from the left and right at x=10.

lim f(x)=

x->10^-

lim f(x)=

x->10^+
