input output which ordered pair needs to be removed in order for the mapping to represent a function? (-3, -4) (-2, -1) (1, -3) (3, 7)
Answer
Explanation:
Step1: Recall function definition
A function has one - to - one or many - to - one mapping, not one - to - many. Here, the input value of - 2 is mapped to both - 1 and - 3.
Step2: Identify the pair to remove
To make it a function, we need to remove one of the pairs with input - 2. The pair (-2, -1) should be removed.
Answer:
(-2, -1)
