use the relation {(1,3);(2,4);(3,5);(4,6)}

b: What is the range of the function?

To see whether a relation is a function, the best way to do it is to remember that a particular value of x should direct to only one unique value of y. Going by this, you can hopefully eyeball that the relation is  a function. And as for range, it is the set of all y coordinates of the function.Hope this helped you.

In the given relation, a value of x does not point towards more than one value of y.So, it is  a function.

anonymous · Answer

Range={3,4,5,6} , which is the set of all y-coordinates of the function.
