Algebraically…using limits• Anytime you are given an equation – factor first!• Take the limit at all points of discontinuity!

• If you get then you have a hole at that point…• You will have to find the (x,y) coordinate of the hole!

• If you get then you have a VA at that x-value…• You will have to do limits to talk about behavior and be able to

graph without a calculator!
