Basic Rational Functions Graphs

Which asymptotes are determined by looking at the denominator of a function? 

• vertical

• horizontal

• slant

• none

Which is the graph of the rational equation:

• 
• 
• 
• 

Write an equation for a rational function with an x-intercept of (–1, 0), a hole at x = 3, and a VA at   x = 4. 

• y= (x-1)(x+3) / (x+4)(x+3)

• y= (x-4)(x-3) / (x+1)(x-3)

• y= (x+1)(x-3) / (x-4)(x-3)

• y= (x+4)(x+3) / (x+1)(x+3)

What value of the denominator will make the function discontinuous?

• -1

• 1

• 0

• 2

What are the vertical and horizontal asymptotes of the following function?

• vertical asymptote is 3 and horizontal asymptote is 1

• vertical asymptote is 1 and horizontal asymptote is 3

• vertical asymptote is 1 and horizontal asymptote is -3

• vertical asymptote is -1/3 and horizontal asymptote is 1

• vertical asymptote is 3 and horizontal asymptote is -1/3

The graph of a rational function can best be descirbed as

• A line

• A parabola

• A gradual curve

• A hyperbola

• A circle

The asymptote(s) of the parent function of rational functions is/are:

• x=0 

• y=0 

•  x=1

• y=1

• x=0 and y=0

A rational function in the form shown has

• x= h as its horizontal asymptote and y=k as its vertical asymptote

• x=h as its vertical asymptote and y=k as its horizontal asymptote

• x = -h as its horizontal asymptote and y=k as its vertical asymptote

• x = -h as its vertical asymptote and y=k as its horizontal asymptote

• Not sure what an asymptote is but I feel none of the answers listed are correct
