Rational Functions

What is the equation of the graph?

• 
• 
• 
• 

Which is NOT a reason that there is a hole in the graph?

• The function has an undefined value

  at x = 2

• The hole is near the horizontal asymptote

Which is NOT a description of an end behavior for this graph?

• x = 5

• x = -5

• x = 5, x = -5

• x = 6, x = -3

Answer explanation

Vertical asymptotes are the undefined values of the function.

Set the denominator equal to 0 and solve for x: (x+5)(x-5) = 0

• y = -3

• y = 1

• y = 5, y = -5

• y = 0

• y = -2 and y = -4

• y = 1

• y = 1, y = -1

• y = 0
