Graphing Rational Functions

Find the horizontal asymptote.

• y = -2
• none
• y = 0
• y = 1/2

What are the asymptotes?

• x=-2 and y=-1
• x=-2 and y=1
• x=2 and y=1
• x=2 and y = -1

When finding the Horizontal asymptotes of a function, you should be thinking...

• "Set Bottom = to Zero"
• "Top = 0"
• "f(0)"
• "Look at the Degree of the top and bottom..."

What are the equations of the asymptotes of the given graph

• x=1, x= 2, y =1, y= 2
• x= 2, x= -2, y = 1
• x=2 and  y= -1
• x=1, y =2, y = -2

Which asymptote(s) are determined by looking at the denominator?

• vertical
• horizontal
• slant
• none

What is the equation of the horizontal asymptote of the given function?

• y = 2
• x = 1
• There isn't one
• y = 5

What is the horizontal asymptote to this function?

• x=4
• y=0
• none
• y=4

What is the horizontal asymptote?

• y = 2
• y = -2
• x = 2
• y = 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

What is the definition of an ASYMPTOTE?

• A curved line. 
• A line that only touches the origin. 
• A line that only lives on the first quadrant. 
• A line that a curve approaches, as it heads towards infinity.
