Question

Is the following a Function?

Input: -7, 2, -1, 5
Output: 1, 3, 5, 8

Answer 1

The given set of input-output pairs does represent a function because every input is associated with exactly one output, satisfying the definition of a function.

Step-by-step explanation:

To determine if the relationship given is a function, we must check if every input has exactly one output. In other words, for a set to be a function, each value in the domain (inputs) should be paired with one and only one value in the range (outputs).

Given the inputs and outputs:

• Input: -7, 2, -1, 5
• Output: 1, 3, 5, 8

We can see that each input value is associated with a different output value. Since no input is associated with more than one output, the given set of input-output pairs does represent a function.
