Class 12 Maths · Relations And Functions · Mcq Single Correct #138

The proposed rule \(f:\mathbb R\to\mathbb R\), \(f(x)=1/x\) for every real x, is best described as

✅ Step-by-Step Solution

Final Answer: Option (D): Not a function on all of the stated domain
  1. At the real input 0 the expression 1/x is undefined. Thus the proposed rule fails to define a function on all of R. The PDF detailed solution selects d, contradicting the printed key a.
