Section 1.6: Problem 1 {1 point] Previous Problem Problem List Next Problem Atunction is said to have a vertical asymptote wherever the limit on the left or right (or both) is either positive or negative infinity. For example, the function x) 2 % has a vertical asymptote at 2: = 7. For each of the following limits, enter either 'P' for positive innity, 'N' for negative innity. or 'D' when the limit simply does not exist.

If there are no asymptotes of a given type, enter NONE. If there is more than one asymptote of a given type, give a comma-seperated list (i.e.: 1, 2,...).
