Determine if the Relation is a Function (0,1) , (1,-2) , (2,-3) , (3,-2) , (4,1)

$(0, 1)$ , $(1, - 2)$ , $(2, - 3)$ , $(3, - 2)$ , $(4, 1)$

Since there is one value of $y$ for every value of $x$ in $(0, 1), (1, - 2), (2, - 3), (3, - 2), (4, 1)$ , this relation is a function.

The relation is a function.
