Q. Which of the following statements is true for a function f(x)?

f(x) cannot cross its horizontal asymptote(s).
A vertical asymptote can only be drawn at x = a if f(a) is undefined.

f(x) must approach its horizontal asymptote as x approaches ∞.
A vertical asymptote is drawn at x = a if at least one of  is either ∞ or -∞

Q. Find all vertical asymptotes (if any) of the function

x = 2 and x = -2

x = 0

x = 0, x = 2, and x = -2

f(x) has no vertical asymptotes
Q. The function  has

a hole at x = -10 and a vertical asymptote at x = 7

a vertical asymptote at x = -10 and a hole at x = 7

vertical asymptotes at x = -10 and x = 7

holes at x = -10 and x = 7

Q. Which statement is true?

Q. The function   has

a horizontal asymptote
a slant asymptote
a curvilinear asymptote
none of the above
Q. The function  has

a horizontal asymptote at x = 0

a horizontal asymptote at y = 0

a horizontal asymptote at x = 3

a horizontal asymptote at y = 3

Q. Which of the following pictures could be a graph of the function ?

Q. Which of the following pictures could be a graph of the function

Q.

0
-1
-∞
Q. For the function  ,

which function should we choose for p(x) to ensure that ?

p(x) = ln x

p(x) = 1000x2 + 4x + 6

p(x) = ln x + x2

p(x) = 2x
