(a) Classify all the discontinuity of the function f(x)
removable
1. x = 0
not a discontinuity 2. x = -5
infinite essential
3. x = 2
(b) The only removable discontinuity is at x = 0
should redefine f ( 0
=
(c) The only essential discontinuity is at x = a =
To remove this discontinuity, we
We know that
lim f(x) =
x-a-
lim f(x) =
x→a+
lim f(x) =
x a
Remember to write INF for +∞, MINF for -∞ and DNE for "does not exist".
