2-71.

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 *x* = − 5, the limit does not exist. But we can still determine if *f*(*x*) approaches +∞, −∞ or both. We are to determine if there is agreement among the limits as *x* → − 5 from each side.

Test a point close to *x* = −5 but a little bit larger:

Therefore, *x* → −5^{+}, *f*(*x*) → −∞

Evaluate and simplify.
