= A function f(x) is said to have a jump discontinuity at x = a if: 1. lim f(x) exists. 1 → 2. lim f(x) exists. 1+a+ 3. The left and right limits are not equal. = 2 I +7 8.0 1 if : <7 Let f(x) = if <> 7 Show that f(x) has a jump discontinuity at x = 7 by calculating the limits from the left and right at = 7 lim f(x) = = I →7 = lim f(x) = 1+7+ Now for fun, try to graph f(x).
Determine the set of x-values where f(1) = 14 2 + 10 + 5x is continuous, using interval notation.
