If the function is an exponential function, is 2x+3y=6 a function or relation?

The classic way of writing a function is "f(x)".You will see that there are other ways.

We will look at the general idea of a function instead of looking at specific functions.

"f" is the most common name, but we can have other names as well.

"x" is just there to show us where the input goes and what happens to it.

We said that a function was like a machine.A function doesn't actually destroy what we put into it.

It is not a function when a relationship does not follow the rules.

No vertical line crosses more than one value on a graph.

You can find out more about the types of functions that have stricter rules.

Functions usually work on sets with many elements, but my examples have a few values.

Functions have been used in mathematics for a long time and there are many different ways of writing them.

2(4), (2,5), (7,3) is not a function because it means that 2 could be related to 4 or 5.
