2-65.

As the coffee cools, temperature will drop...

But will it approach a constant temperature (a horizontal asymptote)?

Or will it drop without bound (such that as *x* → ∞, °F → − ∞)?

If you sketched a horizontal asymptote, then the limit should approach a constant value.

What does that horizontal asymptote represent? (use words)

If your sketch shows the temperature → −∞, then the limit does not exist, but approaches −∞.

What does that represent? (use words)
