What does the graph look like to the right?

What does the graph look like to the left?

Since there is a vertical asymptote at

, the limit does not exist. But we can still determine ifapproaches, or both. We are to determine if there is agreement among the limits as from each side.Test a point close to

but a little bit larger:Therefore,

Evaluate and simplify.
