Let

A = R - \left\{ 3 \right\},B = R - \left\{ 1 \right\}.

Let

f:A \to B

be defined by

f\left( x \right) = \frac{{x - 2}}{{x - 3}}

.Then,

View answer and explanation

Correct option: A

f is bijective

Option A (f is bijective) is correct because the function f is both injective (one-to-one) and surjective (onto), thus bijective.
