Step-by-step explanation:
You can obtain any two points on the graph of and use it to draw its graph.
When x=0,
So you plot (0,2)
When x=1,
You again plot (1,-71).
With a straight edge you can now draw a straight line through the two points.

In the limit
we're interested in the value that converges to as
gets closer to
. So in fact
.
In the given example, is factorized to reveal a common factor of
in the numerator and denominator. We have
if
, so
so we can simplify
and *remove* the discontinuity.
Then
