which ordered pair could be removed so that the set of ordered pairs is a function? (4, -2) (-3, 2) (3, 4) (1, 1)
Answer
Explanation:
Step1: Recall function definition
A function has one - to - one or many - to - one mapping, i.e., for each x - value, there is exactly one y - value.
Step2: Identify repeated x - values
From the graph, we see that x = 4 has two y - values (y = 4 and y=-2).
Answer:
(4, -2)
