Intro Rational Functions

Rational functions always have exactly 1 vertical asymptote.

• True

• False

• y = -7

• x = 7

• y = 0

• x = -7

This rational function is undefined at...

• x = 4

• x = -4

• x = 0

• x = 5

Which rational function has a vertical asymptote at x = -3

What is the equation of the rational function graphed?

• y = -4

• y = 2

• y = 3

• y= 4

What is the equation of this rational function

What's the horizontal asymptote of the function?

• y = 3

• No horizontal asymptote

• y = 0

• y = 2
