Class 12 Maths · Relations And Functions · Mcq Single Correct #44

\(A=\{1,2,3,4\}\), \(B=\{1,2,3,4,5,6\}\), and \(f:A\to B\) is defined by \(f(x)=x+2\) for all \(x\in A\). The function \(f\) is

✅ Step-by-Step Solution

Final Answer: Option (C): One-one
  1. Distinct inputs have distinct images. The image is \(\{3,4,5,6\}\), so it is not onto \(B\).
