Answer:

Option C

{-1,3,5}

Step-by-step explanation:

A mapping is a subset of ordered pair (x,y) where x belongs to first set and y belongs to second set.

Hence a mapping is a subset of cartesian product AXB.

Here A = {-2,1,3,5} and

B = {2,4,6,8}

Ordered pair given by the mapping is

(-2,1) (3,6) and (5,8)

In other words, -2 is mapped on to 1, 3 to 6 and 5 to 8

Domain = set of elements in the I set which are mapped

= {-1,3,5}
