Question

How do you find the domain and range and determine whether the relation is a function given {(3,4), (4,3), (6,5), (5,6)}?

Answer 1

Domain `=(3,4,6,5)`
Range `=(4,3,5,6)`
It is a function

Explanation:

`{(3,4),(4,3),(6,5),(5,6)}`

Domain is the set of all `x` coordinate, so domain `=(3,4,6,5)`

Range is the set of all `y` coordinate, so range `=(4,3,5,6)`

From this, we can find out that every element in `x` has only one element in `y`.

So it is a Function.
