What are the asymptotes?

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

Find the horizontal asymptote.

• y = -2
• none
• y = 0
• y = 1/2

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

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

Where is the axis of symmetry for this parabola?

• x = −1
• x = 0
• y = 3
• x = −3
