मान लीजिए f : &mathbb; - {2, 6} → &mathbb; एक वास्तविक मान वाला फलन है जो f(x) = x2 + 2x + 1x2 - 8x + 12 के रूप में परिभाषित है। तो f का परिसर (range) है:

Consider the following statements regarding a Bijective Function: Statement 1: A function is classified as bijective if it is both injective (one-to-one) and surjective (onto). Statement 2: Bijective functions lack the property of invertibility because they do not establish a one-to-one correspondence between elements.

Let M be the set of all 2 × 2 matrices with entries from the set R of real numbers. Then the function f : M → R defined by f(A) = |A| for every A ∈ M is:
