Limits Graphs Analytically and Asymptote

Which of the following actions are appropriate for finding a limit at infinity? Look for multiple answers.

• If the function is polynomial, look at rules for end behavior.

• If the function has a HA, that will determine the limit at infinity.

• If the function has a slant asymptote, look at the end behavior of that line (the slant asymptote)

• Look at the function graphically to determine end behavior.

Which statement is true about slant asymptotes?

• Slant asymptotes can be a vertical or horizontal line graphically.

• Slant asymptotes are oblique (not purely vertical or horizontal) lines graphically.

• Slant asymptotes occur when the degree of the denominator is greater.

• Slant asymptotes occur when the degree of the numerator and denominator are equal.
