### Question:

How to declare relation as a function?

### Answer:

Step 1

In this task, we have to figure out if a relationship is a function and then explain why it is a function. We get the following information:

Each value of x must have exactly one value of y for it to be called a function.

Step 2

This map has a reason for being made. Because each xx value can only have one y value.

A function is a relationship that says for every input, there should only be one output. We can also say that a function is a special kind of relationship (a set of ordered pairs) that follows a rule, which is that each X-value should be linked to only one Y-value. As an example: Domain. Range.
