Assertion (A): A function \(f : (0, 2) \to [2, 14]\) defined by \(f(x) = 3x^2 + 2\) is bijective.
Reason (R): A function \(f : X \to Y\) is bijective if it is one-one and onto both.
- Both (A) and (R) are true and (R) is the correct explanation of (A).
- Both (A) and (R) are true but (R) is not the correct explanation of (A).
- (A) is true but (R) is false.
- (A) is false but (R) is true.
Answer
(D) (A) is false but (R) is true.
