• Horizontal asymptote: No horizontal asymptote
• C)Domain: all real numbers x except x = 3 Vertical asymptote: x = 3
• Horizontal asymptote: No horizontal asymptote
• D)Domain: all real numbers x except x = 3 Vertical asymptote: x = 3
• Horizontal asymptote: y = 2
• E)Domain: all real numbers x Vertical asymptote: x = -3
• Horizontal asymptote: y = 0
