This week in math we learned about range and domain, which is also x and y or input and output. One thing we learned was finding the x and y intercepts, to find the intercepts you need the coordinates of x and y and to do that when you find one of the intercepts the other is “0” for example if our finding the “x” intercept “y” is 0.

Relation, is a relation is a set of inputs and outputs, often written as ordered pairs input, output

Functions, is a function is a relation in which each input has only one output.

This picture shows that this is a function because the dots are not right on top of each other or bellow.

If the dots where in on top or bellow each other they would be relations.
