This idea is better illustrated in the following example. ![]() ![]() Then the domain of the piecewise function is the concatenation of these domains, and the range of the piecewise function is the contatenation of the ranges of the functions on their corresponding domains. Piecewise functions are defined using the common functional notation, where the body of the function is an array of functions and associated subdomains. To identify the domain and range of a piecewise function, we recall that a piecewise function is defined by different functions each with corresponding domains. We’ll now look at some functions that are defined by different formulas at different inputs. In this course so far, we’ve mostly studied functions that are defined by a single formula. In the first region, \(x \ge 3\text\) as shown in Figure144. Interactive graphical lesson on piecewise-defined functions, step functions, and the floor and ceiling functions. Half-Angle and Angle Sum and Difference Identities.Introduction to Trigonometric Identities.Additional piecewise functions include the Heaviside step function, rectangle function, and triangle function. A common example is the absolute value, (1) Piecewise functions are implemented in the Wolfram Language as Piecewise val1, cond1, val2, cond2.
