The function is
.
When
tends to
from the right side,
is a small positive number.
Thus, the quotient
is a large positive number and
approaches infinity from the right of
.
So
.
increases without bound as
approaches
from the right.
Verify the limit by using the table.

As limit in which
increases without bound as
approaches
from the right is called as an infinite limit.
Therefore,
