Topics in Relations And Functions
1
1.2 Types of Relations - Problem-Solving Approach
- A relation R from set A to B is a subset of A × B, i.e., R ⊆ A × B
- Domain of R = {a ∈ A : (a,b) ∈ R for some b ∈ B}
- Range of R = {b ∈ B : (a,b) ∈ R for some a ∈ A}
2
1.3 Types of Functions - Step-by-Step Analysis
- A function f: A → B assigns exactly one element in B to each element in A
- Functions can be one-one (injective), onto (surjective), or bijective (both)
- Total functions from A to B = [n(B)]^[n(A)]
3
1.4 Composition and Invertible Functions - Advanced Problem Solving
- Composition (g∘f)(x) = g(f(x)) - apply f first, then g
- Composition is associative: f∘(g∘h) = (f∘g)∘h but generally not commutative
- Function has inverse if and only if it is bijective
