Two young mathematicians discuss the eating habits of their cats.

Continuity is defined by limits.

Here we use limits to ensure piecewise functions are continuous.

Here we see a consequence of a function being continuous.

Here is an opportunity for you to practice using the definition of continuity.

On this card, we investigate what is meant by the maxima and minima of a function.

On this card, we will determine the conditions that guarantee a continuous function has an absolute maximum and minimum.

Two young mathematicians discuss what curves look like when one ‘‘zooms out.’’

We want to solve limits that have the form nonzero over zero.

We explore functions that ‘‘shoot to infinity’’ at certain points in their domain.

We explore functions that behave like horizontal lines as the input grows without bound.

Here is an opportunity for you to practice evaluating limits that involve infinity.

Here is an opportunity for you to practice evaluating many different types of limits.
