(a) A function, f say, is a set of ordered pairs in which no two distinct elements have the same first entry. If A is a source set of f and B is a codomain of f then we use the notation f : A→B marks 1 2 1(c) (i) The Modulus or Absolute Value function mod ( x )≡∣x∣ f : R→R mod ( x ) or ∣x∣= x x >0 0 x=0 −x x ∈0 4 1 marks Properties y (i) ∣x∣>0 (ii) ∣...

### **Relations** A **relation** in mathematics is a way to associate elements from one set with elements of another set. Formally, a relation (R) from set (A) to set (B) is defined as a subset of the Cartesian product (A times B), which consists of all ordered pairs ((a, b)) where (a in A) and (b in B). #### **Key Concepts in Relations:** 1. **Domain**: The set of all first elements (inputs) of the ordered pairs in the relation. For example, in the rel...

A set is a collection of distinct objects, called elements or members of the set. Sets are usually denoted by capital letters, such as A, B, and C. Sets can be finite, containing a specific number of elements, or infinite, containing an infinite number of elements. A function is a mathematical relationship between two sets, called the domain and the codomain. The domain is the set of input values, and the codomain is the set of output values. A function assigns to each element in the domain e...
