Find the value of k for which f(x) = kx2 for x ≤ 2 and f(x) = 3 for x > 2 is continuous at x = 2.
Original Khojo Papers practice question — not from a past board paper.
Answer
k = 3/4
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
For continuity the left-hand limit 4k must equal the right-hand limit 3, so k = 3/4.
