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

$(1, 1)$ , $(2, \frac{1}{2})$ , $(3, \frac{1}{3})$ , $(4, \frac{1}{4})$

Step 1

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