which has vertical asymptotes (i.e. infinite discontinuities) whenever the denominator is zero. This happens for
(where is any integer)
So the graph of has vertical asymptotes whenever and .
4) Given
we have the one-sided limits
and
The one-sided limits don't match, so the two-sided limit does not exist. In other words, the limit does not exist at because the function approaches different values from the left and right side of .
Answer: Yes ,because it isn't the same the number since the number of digits aren't the same so you make it the same number of digits by putting 0 in the back so 1.7 turns to 1.700 to make it the same digits of 1.700.
