The graph approaches y = 0 as x → ±∞. What is the horizontal asymptote rule?
ANumerator degree < denominator degree → HA y = 0
BNumerator degree > denominator → HA y = 0
CNo HA
DEqual degrees → ratio of leading coefficients
Explanation
When numerator degree is strictly less than denominator degree, the horizontal asymptote is y = 0.
