100. 1. Limits
Definition
If f(x) approaches some finite number L as x approaches c,
then we say that the limit of f(x) as x approaches c is L
and symbolically write
lim f (x) = L
x→c
101. 1. Limits
One-sided limits
lim f (x)
− x approaches c from the left
x→c

Two-sided limits
lim f (x) = L if and only if x→c− f (x) = L and x→c+ f (x) = L
