#### Important Terms on Relations and Functions

- Relation R from a non-empty set A to a non-empty set B is a subset of A × B.
- If n(A) = p, n(B) = q then n(A × B) = pq and number of relations = 2^pq.
- A relation f from a set A to a set B is said to be a function if every element of set A has one and only one image in set B.
- Let A and B be two non-empty finite sets such that n(A) = p and n(B) = q then number of functions from A to B = q^p.

##### Extra Important Questions on Relations and Functions

- If A and B are finite sets such that n(A) = 5 and n(B) = 7, then find the number of functions from A to B.
- If A = {2, 4, 6, 9} B = {4, 6, 18, 27, 54} and a relation R from A to B is defined by R = {(a, b): a belongs to A, b belongs to B, a is a factor of b and a < b}, then find in Roster form. Also find its domain and range.
- Determine a quadratic function (f) is defined by f(x) = ax² + bx + c. If f(0) = 6; f(2) = 11, f(–3) = 6.
