Function Notation Equation Examples Title 3 02 Function Notation And Graphs Essential Questions 3 02
The following diagram shows an example of function notation.
Function notation equation examples. The independent variable terms with x go on the right side of the equation while fx goes on the left side. This is a special notation used only for functions. For example function notation for a quadratic equation is fx ax 2 bx c for constants a b and c. Add 1 if we use x to represent our domain guys heres the official notation.

The typical notation for a function is fx. 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.
But function notation gives you greater flexibility than using just y for every formula. Function notation makes it easy to calculate the value of a function in terms of the independent variable. Scroll down the page for more examples and solutions of function notations. In the previous lesson you learned how to identify a function by analyzing the domain and range and using the vertical line test.
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. This is read as f of x this does not mean f times x. For example y 2x 3 is my favorite linear function. Sal uses function notation to help frank figure out how much water he can put in his balloon.
Function notation is an efficient and effective way to display. Function notation is the way in which a function is written to precisely convey information. 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. Now we are going to take a look at function notation and how it is used in algebra.
Lets take a look at a couple of the boxes in our last lesson. 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. And x 1 guys spit out. Sal uses function notation to help frank figure out how much water he can put in his balloon.
Examples solutions videos worksheets games and activities to help algebra 1 students learn about equations and the function notation. You read this guy fx as f of x x guys go in.
