फलन f, जो f(x) = √(4 - x) + 1√(x2 - 1) द्वारा परिभाषित है, का प्रांत (Domain) किसके बराबर 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:
