Algebra 2 Test 10 - Rational Functions

What are the x-intercepts?

• x= 2/3
• x= 4, x = -2
• x= -8, x = 1
• x= -4, x = 2

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

How is this function transformed from the parent function?

• Translated left and up
• Translated right and up
• Translated left and down
• Translated right and down

What is the horizontal asymptote? 

• x = 2
• x = 7
• y = 2
• y = 7

Where is the removable discontinuity?

• x=2
• x=2 and x=3

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

• Numerator
• Denominator
• Right side 
• Left side

How do you find the y-intercept?

• replace all x-values with 0

• replace all y-values with 0

• set denominator equal to 0

• compare the degrees of the numerator and denominator

How do you find the x-intercept?

• replace all x-values with 0

• replace the y-value with 0 or make the numerator equal 0

• set denominator equal to 0

• compare the degrees of the numerator and denominator

How do you know if a factor in the denominator is a hole instead of a V.A. ?

• It cancels out

• it equals 0

• you set the numerator equal to 0

• you compare the degrees

The first thing you should do to find all the attributes for a rational function is...

• Factor it all out

• Find the V.A.

• Find the H.A.

• Find the x / y intercepts
