Question

Q2.Write domain, Co-domain and Range and specify the type of Function for the following: 4
A={1,2,3,4} B={a,b,c,d}
a.f={(1,a), (2,b), (3,c), (4,d)}
b.f={(1,a), (2,a), (3,b)}
A={1,2} B={a,b,c}
c.f={(1,a), (2,b)}
d.f={(1,a)}

Answer 1

Answer:

First component known as Domain.

Second component known as Range.

Reflexive function means first component = second component.

symmetric function means a,b=b,a

Transitive function means a,b = b,c then also a,c
