Learn how to sketch graphs of piecewise functions using Desmos graphing calculator through solved examples mentioned in my article. One “tooth” of the function constructed from two piecewise functions: f(x) = x (for 0 ≤ x ≤ 1) and f(x) = 2 – x (for 1 ≤ x ≤ 2). Press WINDOW to access the Window editor. In other words, each individual “tooth” can be built with one or two functions.Īs an example, the following graph of one tooth (actually a sawtooth function) is represented by two different functions: one for the upslope and one for the downslope: The easiest way to think of them is if you drew more than one function on a graph, and you just erased parts of the functions where they aren’t supposed to be (along the ’s). One relatively simple way to create a graph of the triangle wave function is to construct a series of piecewise functions. Piecewise functions (or piece-wise functions) are just what they are named: pieces of different functions (sub-functions) all on one graph.

Graph of f(x) = (2/π) sin -1 created on Ĭreating a Triangle Wave with Piecewise Functions Piecewise functions graphs Worked example: domain & range of step function Worked example: domain & range of piecewise linear functions Absolute value & piecewise functions: FAQ Math > Algebra 1 > Absolute value & piecewise functions > Piecewise functions Piecewise functions graphs CCSS.Math: HSF.IF.C.7, HSF.IF.C. How to Graph Piecewise Functions on Calculator w/ Domain Limits Pre-Calculus Math by Jill b. For example, the following graph uses a combination of sine and inverse sine to create the triangular waves: Learn Desmos: Function Notation Pro-Tips You can evaluate a function at a certain point: You can use the notation f (x,y), for example, to define a function with more than one variable: Defining a function once allows you to use this function within other functions. Perhaps the simplest way to approximate the shape is with the sine function and inverse sine function. An alternate definition is as the absolute value of the sawtooth wave, but that definition also includes the floor function. This may be a helpful definition, but with the inclusion of a floor function, it isn’t graphable as-is. One way to define the function is in terms of the floor function (⌊ x ⌋ ):ĭefinition of the triangle wave function.
