lim_(x→∞) (3x² - 5)/(7x² + 2) =
AInfinity
B-5/2
C3/7 (ratio of leading coefficients)
D0
Answer & Solution
Correct answer: C. 3/7 (ratio of leading coefficients)
Divide numerator and denominator by x²: (3 - 5/x²)/(7 + 2/x²) → 3/7 as x → ∞. (For polynomials of same degree, ratio is of leading coefficients.)
