Solution:We have, limx→∞ x2−x+1−(ax+b)=0⇒limx→∞ x2−x+1−(ax+b)2x2−x+1+(ax+b)=0⇒limx→∞ x21−a2−x(1+2ab)+1−b2x2−x+1+ax+b=0⇒1−a2=0 and 1+2ab=0⇒a=±1 and b=∓1/2.For a=−1 and b=1/2 we observe that limx→∞ x2−x+1−ax−b=limx→∞ x2−x+1+x−12→∞Hence, a=1 and b=−12 Related content Class 9 Science MCQ Chapter 12 Sound CBSE Class 12 English MCQ with Answers (Flamingo & Vistas) CBSE Class 7 Science MCQ Questions with Answers CBSE Class 12 Subject Wise MCQ 2024-25 ICSE Class 10 Toppers List 2024 Available Tenses Worksheet for Class 10 CBSE Class 7 Science Chapter 3 Heat MCQ Questions with Answers Nephron Diagram Class 10 CBSE Class 7 Science Chapter 2 Nutrition in Animals MCQ with Answers Rabindranath Tagore Jayanti 2024
