About 12 Maths Exercise 1.2

In Exercise 1.2, the questions are based on concept of one – one, onto, injective, surjective, bijective, invertible function, etc. If the function is invertible, then we have to find inverse also. If for each element in domain, there is one and only one element in co-domain, then it is called one-one. Similarly, if for each element in range, there is one and only one element in domain, then it is onto. When a function is one – one as well as onto, it is said to be invertible function.

Important Terms related to Exercise 1.2
    1. One-One Function :f : A → B is said to be one-one if distinct elements in A have distinct images in B. i.e. ∀ x1, x2 ∈ A such that x1 ≠ x2 ⇨f (x1) ≠ f(x2).
    2. Onto function (surjective): A function f :A→B is said to be onto iff Rf = B i.e. ∀ b ∈ B, there exists a ∈ A such that f (a) = b
    3. Bijective Function : A function which is both injective and surjective is called bijective function.
