# Determine if the Relation is a Function (x,-2) , (r,-2) , (y,-2) , (f,1)

(x,-2) , (r,-2) , (y,-2) , (f,1)
Since there is one value of y for every value of x in (x,-2),(r,-2),(y,-2),(f,1), this relation is a function.
The relation is a function.
Determine if the Relation is a Function (x,-2) , (r,-2) , (y,-2) , (f,1)
