Solving Rational Functions Practice

A vertical asymptote is found by setting the _________ equal to zero and solving for x.

• Numerator

• Denominator

• Right side 

• Left side

Find the horizontal asymptote.

• There is no horizontal asymptote.

• y=-2

• y=2

• y=0

• There is a hole at x=3

• There is a hole at x= -2

• The horizontal asymptote is at y=0

• The domain is ℝ; x ≠2,3

Graph the function.

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

• Vertical Asymptote. at x = -3 and x = 1

• Hole at (1, -2)

• Horizontal Asymptote at y = 2

• x-intercepts at (-1,0) and (1, 0)

Select all of the true statements.

• A hole occurs at (3,-20)

• vertical asymptote at x=3

• vertical asymptote at x=5

• A hole occurs at (5,72)

What are the asymptotes?

• x = -3        y = 1  

• x = 3         y = 1
