Relations And Functions — Syllabus & Topics
Topics covered in Relations And Functions for BITSAT Mathematics.
Topics in Relations And Functions
Cartesian Product of Sets
- Cartesian product X × Y is the set of all ordered pairs (x,y) where x ∈ X and y ∈ Y
- If n(X) = p and n(Y) = q, then n(X × Y) = pq
- Order matters in Cartesian products: X × Y ≠ Y × X (unless X = Y)
Relations
- A relation R from X to Y is any subset of X × Y
- Domain of R = set of all first elements in ordered pairs of R
- Range of R = set of all second elements in ordered pairs of R
Functions
- A function f: X → Y is a special relation where each element in X maps to exactly one element in Y
- For functions: Domain = X, Co-domain = Y, Range ⊆ Y
- Vertical Line Test: A graph represents a function if every vertical line intersects it at most once
Types of Functions
- Identity Function: f(x) = x for all x in domain
- Constant Function: f(x) = c for all x in domain
- Polynomial Function: f(x) = a₀ + a₁x + a₂x² + ... + aₙxⁿ
