## What does the big S mean in math?

5. It is the symbol for the Integral; it is a stylized 'S' because the concept of the integral is a related to the Sum, which starts with S. (the mathematical symbol for Sum is a capital sigma, ∑ -- which is S in the traditional Grek alphabet from which mathematics borrows so many symbols.)

## What does element of R mean?

## What is an example of not a function?

Horizontal lines are functions that have a range that is a single value. 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.

## How do you determine if it's not a function?

A WAY easier (and faster), way to know if it is a function is to see if there are two of the same x-intercept (which make a vertical line). If there is, then it is NOT a function.

## How do you tell if a relation is a function?

How To: Given a relationship between two quantities, determine whether the relationship is a function.

1. Identify the input values.
2. Identify the output values.
3. If each input value leads to only one output value, classify the relationship as a function.

## How can you identify a function?

Relations can be written as ordered pairs of numbers or as numbers in a table of values. By examining the inputs (x-coordinates) and outputs (y-coordinates), you can determine whether or not the relation is a function. Remember, in a function each input has only one output. A couple of examples follow.

## Is a circle a function?

A circle is a set of points in the plane. A function is a mapping from one set to another, so they're completely different kinds of things, and a circle cannot be a function. What you presumably meant to ask is whether the circle is the graph of some function.
