Question

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)

Explanation:

Step1: Recall function definition

A function maps each input to exactly one output.

Step2: Identify duplicate input

Input value -2 maps to 2, -3, and -1.

Step3: Match to ordered pair

The ordered pairs for input -2 are (-2,2), (-2,-3), (-2,-1). Among the options, (-2, -1) is one of these. Removing it leaves -2 with a single output.

Answer:

(-2, -1)
