Pre-Cal Review (Day 2)

What is an asymptote?

How many different kinds are there?

Asymptotes (Discontinuity)

There are vertical asymptotes when?

There are horizontal asymptotes when?

BOBO BOTN EATS DC

Set denominator equal to zero

Who knows what a hole in a function is?

How can you tell where a hole is by looking at a function?

Process

1. Find your holes if any. (Factor and cancel)

2. Find the horizontal asymptotes BOBO BOTN EATS DC

3. Find your vertical asymptotes (set denominator = 0)

Find the vertical & horizontal asymptotes and the holes in the functions

Find the areas of discontinuity.

y=

Find the discontinuities.
