A) As x approaches positive infinity, y approaches negative infinity. As x approaches negative infinity, y approaches negative infinity.
B) As x approaches positive infinity, y approaches positive infinity. As x approaches negative infinity, y approaches the asymptote y = 4.
C) As x approaches positive infinity, y approaches positive infinity. As x approaches negative infinity, y approaches the asymptote x = 4.
D) As x approaches positive infinity, y approaches the asymptote y = 4. As x approaches negative infinity, y approaches positive infinity.
