Question

What are the outputs of the following function?

{(-3, 2), (-4, 2), (8, 3), (7, 1)}

{1, 2, 3}
{3, 2, 1, 2}
{-3, -4, 2, 1, 7, 8, 3}
{1, 2, 3, -4, 7}

Answer 1

Answer: {1, 2, 3}

Explanation:

Functions

They are relations between input values and output values such that each input has one and only one output.

The function:

{(-3, 2), (-4, 2), (8, 3), (7, 1)}

Consists of four ordered pairs where the first component is the input value and the second value is the output value.

It can be identified that the output values are:

{2,3,1}

In any order, thus the first choice is correct.

Answer: {1, 2, 3}
