And now to describe the behavior of the function. Notice how from the graph. The graph is goingMoreAnd now to describe the behavior of the function. Notice how from the graph. The graph is going uphill from left to right which means the function is increasing.

## How do you tell if a set of ordered pairs is a function?

How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then test to see if each element in the domain is matched with exactly one element in the range. If so you have a function!

## How do you tell which ordered pair is not a function?

A function is a relationship in which one variable is determined by the other variable. In a function each input has exactly one output so if a relationship has an input that has more than one output that relationship is not a function.

## How do you check if it is a function?

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and at any time touches the graph at only one point then the graph is a function. If the vertical line touches the graph at more than one point then the graph is not a function.
