There are other ways of representing this the most common is just using a second variable, like ybut function notation has its advantages. This last example from http: Two lessons ago we had a short look at equations, where one expression was equal to a second expression.

This is especially apparent if you substitute numbers in an orderly manner. If you ever get two different outputs for the same input, you know you are not dealing with a function. That is the function. Secondly, this allows us to show, in our equation, the input - what we are substituting for x.

Thus the need for function notation. You note that the 2 replaced the x in f x. Our answer shows without any doubt that 2 was my input, and 4 is the output. Look at the following examples of trends: Often, we can write this expression just by paying attention to the patterns.

It is often seen like this: This is real data, though is an excellent example that correlation the matching up of data is not causation a linked cause.

A manager or market analyst would likely look at this to try to make predictions about the future. This is read, "The function of x is x plus two" or "f of x equals x plus 2. This will result in the output, the f x. The x, of course, represents one of the variables.

That is where the output value will go, after the x has gone into the function, the machine. A biologist or ecologist might look at this and try to determine what it is about the location and topography land features, surroundings, etc that might cause such a great difference in Acapulco.

They would likely try to create some type of mathematical model that represented this growth to help them with these predictions. Often, we can use this pattern as you may have done in the games above to create the mathematical expression function that represents what is going on.

The following table shows the results of substituting 2,3,4,5,6, and 7 into the function above.

This graph from http: As you put in more numbers for x, you often start to see a pattern in the outputs. The Function Machine 1 and 2 step functions from MathPlayground.

We then evaluate the expression following the correct order of operations, of course, to find the output, what f 2 is equal to.This Algebra Cruncher generates an endless number of practice problems for function notation, f(x), and substituting for X -- with solutions!

Algebra > Functions > Function Notation > Function Notation 1. Function notation is used to indicate that one variable, "f(x)", is a function of the other variable, "x". Write a function using the information given in the word problem.

Next, evaluate the function with specific values for the variable by plugging, or substituting, in the value and solving. While a function doesn't necessarily have to use numbers, this is a math class, so the rest of the examples we'll look at will involve numbers - like these for example: x 2 + 1 and 3(x - 1.
