## Whats a function on a graph?

The **graph** of the **function** is the set of all points (x,y) in the plane that satisfies the equation y=f(x) y = f ( x ) . ... If we can draw any vertical line that intersects a **graph** more than once, then the **graph** does not define a **function** because that x value has more than one output.

## How does a graph work?

**Graphs** have two axes, the lines that run across the bottom and up the side. The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis. The x-axis may contain categories or numbers. You read it from the bottom left of the **graph**.

## Is a graph a description of data?

## Is a circle on a graph a function?

If you are looking at a **function** that describes a set of points in Cartesian space by mapping each x-coordinate to a y-coordinate, then a **circle** cannot be described by a **function** because it fails what is known in High School as the vertical line test. A **function**, by definition, has a unique output for every input.

## Can a straight line be a function?

## What is not a function?

A **function** is a relation in which each input has only one output. In the relation , y is a **function** of x, because for each input x (1, 2, 3, or 0), there is only one output y. : y is a **function** of x, x is **not a function** of y (y = 9 has multiple outputs). ...

## What is an example of not a function?

Vertical lines are **not functions**. The equations y=±√x and x2+y2=9 **are examples** of non-**functions** because there is at least one x-value with two or more y-values.

## Is a graph a function?

The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one **output value** for each **input value**.

## What qualifies a function?

A technical definition of a **function** is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. We can write the statement that f is a **function** from X to Y using the **function** notation f:X→Y. ...
