We like to be able to spot the slope easily m 2 and the y intercept as well b 3. Functions can also be written in the form of fx pronounced f of xwhen someone says y is a function of x it means that the value. Add 1 if we use x to represent our domain guys heres the official notation.

The typical notation for a function is fx.

Function notation equation examples. This is a special notation used only for functions. If youre seeing this message it means were having trouble loading external resources on our website. You read this guy fx as f of x x guys go in. Function notation is an efficient and effective way to display.

This is read as f of x this does not mean f times x. Function notation is the way in which a function is written to precisely convey information. The independent variable terms with x go on the right side of the equation while fx goes on the left side. You may be accustomed to seeing functions written in such a way that y is written as the output of the function and is set equal to some input x.

Scroll down the page for more examples and solutions of function notations. Now we are going to take a look at function notation and how it is used in algebra. In the previous lesson you learned how to identify a function by analyzing the domain and range and using the vertical line test. Sal uses function notation to help frank figure out how much water he can put in his balloon.

For example function notation for a quadratic equation is fx ax 2 bx c for constants a b and c. Function notation formula functions or functional notations are referred by the letter f and written as fx sometimes in the form of gx ha etc. And x 1 guys spit out. Function notation makes it easy to calculate the value of a function in terms of the independent variable.

Most students will be introduced to function notation after studying linear functions for a little while. But function notation gives you greater flexibility than using just y for every formula. Examples solutions videos worksheets games and activities to help algebra 1 students learn about equations and the function notation. Sal uses function notation to help frank figure out how much water he can put in his balloon.

The following diagram shows an example of function notation. For instance your graphing calculator will list different functions as y1 y2 etc so you can tell the equations apart when say youre looking at their values in table. For example y 2x 3 is my favorite linear function. Lets take a look at a couple of the boxes in our last lesson.

Instead of drawing boxes all the time we need a way to talk about functions with math symbols. Function notation is a system of symbols used in mathematics but it is arguably much easier to learn than musical notation.
