The limit on the right of the function
f (
x ) at a point
c is the limit of
f at
c which would be obtained if only values of
x greater than
c were taken into account; more precisely, it is the number
L which has the property that for any positive number
∊ there is a positive number δ so that if
x is in the domain of
f and 0<
x -
c<δ, then |
f (
x ) -
L|<
∊; denoted by

. Also known as right-hand limit.
