Question

Let A={1,2,3,4}andB={4,8,9,10}.A Function f:A to B given by f={(1,4),(2,8),(3,9),4,10)} is a

Answer 1

Explanation:

it is one -to - one function

because one domain have one image

Answer 2

Answer:

one-one function ,onto function.

Explanation:

A)= { 1, 2 ,3 ,4}. and B)= {4, 8, 9,10}

by mapping

1----------4

2----------8

3-----------9

4-----------10

each element of A is related to each element of B

so, it is one - one function.

And range= co-domain

Therefore onto function.
