Question

What is the domain and range for {(2,3), (3,7), (5,-1), (0,0)}?

Answer 1

Domain `= {0, 2, 3, 5}`
Range `={-1, 0, 3, 7}`

Explanation:

Given a finite mapping of `xrarry` defined by the set
`(color(red)(x),color(blue)(y)) = {(color(red)(2),color(blue)(3)), (color(red)(3),color(blue)(7)), (color(red)(5),color(blue)(-1)), (color(red)(0),color(blue)(0))}`

The `color(red)("Domain")` is the set of values for `color(red)(x)`
and
the `color(blue)("Range")` is the set of values for `color(blue)(y)`
