### Example Question #4 : Limits

The speed of a car traveling on the highway is given by the following function of time:

What can you say about the car's speed after a long time (that is, as approaches infinity)?

**Possible Answers:**

The speed of the car approaches infinity.

Nothing can be concluded from the given function.

The speed of the car approaches zero.

The speed of the car depends on the starting speed.

The speed of the car approaches a constant number.

**Correct answer:**

The speed of the car approaches infinity.

The function given is a polynomial with a term , such that is greater than 1.

Whenever this is the case, we can say that the whole function diverges (approaches infinity) in the limit as approaches infinity.

This tells us that the given function is not a very realistic description of a car's speed for large !
