For instance, if we're calculating the price of a tank of gas, the total price would be dependent on the number of gallons purchased, which is independently chosen by the driver. Just remember that the independent variable is the one you choose the input -- the dependent variable is the result of the function the output, or the answer. What about polynomial functions? Polynomial functions are functions that can be written when combining coefficients, variables and exponents.

Look over these polynomial functions:. Each of the above is a function. They each have independent and dependent variables , and they each have a domain and range. Consider asking your question about functions on the algebra section of our message board. What is a function? Such a function would look like: Here are two more examples of what functions look like: Because of that, we sometimes see the function written in this form: What does it mean to evaluate a function?

That means just plug in that value for x and see what you get, like below: In the previous lesson, you learned how to identify a function by analyzing the domain and range and using the vertical line test.

The typical notation for a function is f x. This is read as "f of x" This does NOT mean f times x. This is a special notation used only for functions. However, f x is not the only variable used in function notation. You can use any letters, but they must be in the same format - a variable followed by another variable in parentheses.

Often times functions are written as an abbreviation. For example, if you are writing an equation to calculate the square of x.
