Question 1

Remember: How do you find a Horizontal Asymptote?

Accepted Answer

BOBO, BOTNO, EATSDC

Answer

Where the numerator equals zero

Answer

Where the denominator equals zero

Answer

Where a factor cancels in the top and bottom

Question 2

Comprehend: Compare finding domain to finding range of a rational function.

Accepted Answer

Domain is affected by vertical asymptotes, Range is affected by horizontal asymptotes

Answer

Domain is y, Range is x

Answer

Domain is affected by holes, Range is not

Answer

Domain is left-right, Range is up-down

Question 3

Apply/Predict: What is the x-value of the hole in this function? $\frac{(x+2)(x-8)}{(x-8)(x-2)}$

Accepted Answer

$8$

Answer

$-8$

Answer

$2$

Answer

$-2$

Accepted Answer

$x=7$

Answer

$x=-\frac{3}{2}$

Answer

$x=-7$

Answer

$x=7, x=-\frac{3}{2}$

Question 5

What is the horizontal asymptote for this function? $\frac{2x^2-3x+2}{3x^2-2x+1}$ (Hint: EATSDC)

Accepted Answer

$y=\frac{2}{3}$

Answer

$y=0$

Answer

$y=\frac{3}{2}$

Answer

None
