Question

Determine whether the relation is a function.

(4,0), (4,1), (5,2), (6,3), (6,4)

Answer 1

The relation is not a function.

Explanation:

In order for a relation to be a function, there can only be one output for every x value. If you were to graph this equation, it would not pass the vertical line test, as 4 has two outputs (0 and 1) and 6 has two outputs (6 and 4).
