TopicCurve Sketching
TypeRange restriction with excluded interval (linear/mixed denominator)
DifficultyChallenging +1.2 This is a Further Pure 2 question requiring polynomial division to find oblique asymptote, vertical asymptote identification, and range analysis via completing the square or calculus. While systematic, it demands multiple techniques and the range restriction proof requires algebraic manipulation beyond routine A-level, placing it moderately above average difficulty.
