Question

What is the range of this function?
{ (1, 2) , (-3, 4) , (3, 3) , (0, -9) }

Answer 1

The function is somewhat like this:

Set A = {1, -3, 3, 0}

Set B = {2, 4, 3, -9}

The mapping is:

1 is mapped to 2

-3 is mapped to 4

3 to 3

0 to -9

Range is therefore the elements of the second set {2, 4, 3, -9}
