Question

1. a set of ordered pairs is shown below. choose a value for ( k ) that would make the relations a function. ({(-3, 6), (1, 2), (k, -5), (-4, 7)}) (\boldsymbol{\text{a}}) 2 (\boldsymbol{\text{b}}) -3 (\boldsymbol{\text{c}}) -4 (\boldsymbol{\text{d}}) 1

Explanation:

Step1: Recall function definition

A relation is a function if each input (x-value) has exactly one output (y-value); no repeated x-values are allowed.

Step2: List existing x-values

The given ordered pairs have x-values: $-3, 1, -4$.

Step3: Identify valid k

Choose k not equal to $-3, 1, -4$. From the options, only 2 is not in this set.

Answer:

A) 2
