Rational Functions Test

How do you find the x asymptote no matter what form it is in?

• divide the co-efficients
• set the bottom equal to 0 and solve for x
• opposite whatever is on the bottom
• just always guess 0

The holes of a rational function occur when :

• my pencil pokes a hole in the paper I'm working on
• there is something left in the denominator
• the value of f(0)
• a factor in the denominator cancels with a factor in the numerator
