U2 17-19 Practice (Asymptotes)

Which asymptote(s) are determined by looking at the denominator?

• vertical

• horizontal

• slant

• none

What is the domain and range?

• D : All real number x ≠ -3
  R: All real number y≠ 1

• D : All real number x ≠ 1
  R: All real number y≠ -3

• D : All real number x ≠ 3
  R: All real number y≠ 1

• D : All real number x ≠ -1
  R: All real number y≠ 3

Which is the graph of the rational equation:

• 
• 
• 
• 

Does this graph have any intercepts?

• yes

• no

For this graph what is the the y int

What is the domain of the function?

What is the range of the function?

• All Real #s;  x ≠ 1
• All Real #s;  x = −1
• All Real #s;  x ≠ -2
• x ≠ −2

• The degree of the numerator is greater than the degree of the denominator. "Top-heavy"

• The degree of the numerator is equal to the degree of the denominator.

• The degree of the numerator is less than the degree of the denominator. "Bottom-heavy"

• Rational functions can never have horizontal asymptotes at y=0.
