Rational Functions and Their Graphs

What is the equation of the horizontal asymptote?

• y = 0

• y = -2

• y = 2

• There isn't one

• y = 0
• y = 1/2
• y = 2
• None

What is/are the vertical asymptote(s)?

Remember: factor and simplify!!

• x=-2

• x=2 and x=3

• x=-3

• x=3

As the graph's x-values approach 2 from the left hand side, what is happening to the y-values?

• 0

  level off as it approaches 0

As the graph's x-values approach 2 from the left hand side, what is happening to the y-values?

• 0

  level off as it approaches 0

What are the asymptotes

• x=1, x= 2, y =1, y= 2

• x= 2, x=-2, y = 1

• x=2 y =-1

• x=1 y =2, y =-2

Find the horizontal asymptote.

• None

• y=-2

• y=2

• y=0

What is the Vertical Asymptotes?

Remember: factor and simplify!!

• x= -4

• x= -4,5

• x= -5,5

• x= 4

On a scale of 1-3 how confident do you feel finding the domain of a rational function?

• 1

  bad bad bad

• 2

  i feel okay, but I look back at my notes to be sure

• 3

  i'm confident without notes

• x = -3

• x = -2

• x = -1/2

• x = 2
