consider the relation given by the table
x:1 2 3 5 3 4
y:4 5 7 9 2 2
(a) is this a relation function?

No, because the x-value 3 corresponds to 2 different y-values, 7 and 2.
A function cannot have the same x-value corresponding to two different
y-values.

(b) what is the domain?

The set of all x-values {1,2,3,4,5}

(c) what is the range?

The set of all y-values {2,4,5,7,9}
