Class 12 Maths · Relations And Functions · Mcq Single Correct #135

Let \(A=\{1,2,3\}\), \(B=\{4,5,6,7\}\), \(f=\{(1,4),(2,5),(3,6)\}\). The most specific correct description is

✅ Step-by-Step Solution

Final Answer: Option (B): Injective
  1. Distinct inputs have distinct images, but 7 has no preimage; injective is more specific than simply being a function.
