Rational Functions Mini Review

What is a parent function of a rational function?

What is an asymptote in the context of rational functions?

• A line that a graph approaches but never touches or crosses.

• A line that a graph crosses at one point.

• A line that a graph touches at one point.

• A line that a graph intersects at multiple points.

What are the two types of asymptotes that a rational function can have?

• vertical and horizontal

• positive and negative

• curved and straight

• oblique and diagonal

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

• Numerator
• Denominator
• Right side 
• Left side

• shift diagonally

• shift left and right

• shift up and down

• shift diagonally

• shift left and right

• shift up and down

• x = 0

• x = 1/7

• x = 7

• y = 7

• y = 0

• x = 1/7

• x = 7

• y = 7

What are the asymptotes?

• x = -3        y = 1  
• x = 3         y = 1
• x = -3        y = -1
• x = 3         y = -1

What is the horizontal asymptote on a rational functional when BOTH degrees are EQUAL?

• y = 0

• NO HA
