Three Ways a Graph Can Break

You'll learnto name a break from what the two sides of the graph do, and to tell a denominator zero that makes a hole from one that makes a wall.

One graph with three breaks in it: a hole, a jump, and a place where the curve runs off the page. Walk in from both sides of each one and the two arrival heights tell you which kind it is. Then one formula whose bottom is zero in two places, and the graph does two different things there. Twelve short steps; press Next for each one.

Before you start

What you're looking at

One graph with three breaks in it. Amber walks in from the left, violet from the right. A ring is a height the curve heads for; a solid dot is a value it actually takes.

The question

At each break, what do the two sides arrive at?
