If a relation is a function, how many y-values can each x-value have?
No, see solution.
Practice makes perfect
For a relation to be a function, each x-value can only be paired with one y-value, but one y-value can be paired with multiple x-values.
( -1, 6), ( 1, 4), ( -1, 2), ( 1, 6), ( -1, 5)
Examining the ordered pairs, we can see that there is at least one x-value with multiple y-values. Therefore, the relation is not a function.
