Q. Is this a relation a function? Justify your answer.{(−1,3)(1,0)(2,3)(4,6)}
Identify x-values: Identify the x-values from the given set of ordered pairs. The ordered pairs are {(−1,3),(1,0),(2,3),(4,6)}. The x-values are −1, 1, 2, and 4.
Check for repeats: Check for any repeated x-values. The x-values are −1, 1, 2, and 4. There are no identical values among these x-values.
Determine function status: Determine if the relation is a function. A relation is a function if each x-value corresponds to exactly one y-value. Since there are no repeated x-values, each x-value is paired with only one y-value. Therefore, the relation is a function.
