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

Answer:

(-2, -1)

Explanation:

Step1: Recall function definition

A function has one - to - one or many - to - one mapping. No two different ordered pairs can have the same first element.

Step2: Analyze given pairs

The input value of - 2 is mapped to both - 1 and - 3. To make it a function, we must remove one of the pairs with input - 2. Among the options, (-2, -1) should be removed.
