For f(x) = (2x + 3)/(x - 4), identify the domain restriction and the vertical and horizontal asymptotes. Explain how the formula supports each answer.
Answer
Domain: x ≠ 4; vertical asymptote: x = 4; horizontal asymptote: y = 2.
Reasoning Strategy
Set the denominator equal to zero for the restriction, verify no factor cancels, and compare leading coefficients for end behavior.
