Class 12 Maths · Relations And Functions · Assertion Reason #150

Assertion: The function \(f:\mathbb R\to\mathbb R\), f(x)=x^2, is onto. Reason: A function is onto exactly when its range equals its codomain.

✅ Step-by-Step Solution

Final Answer: Option (D): A is false, but R is true.
  1. The assertion is false because negative real values are missed; the reason is the correct definition.
