In this explainer, we will learn how to find the domain and range of a piecewise-defined function. We start by recalling what is meant by the domain and range of a function. Definition: Domain and Range of a Fu
Sometimes, we come across a function that requires more than one formula in order to obtain the given output. For example, in the toolkit functions, we introduced the absolute value function f(x)=∣x∣f(x)=∣x∣. With a domain of all real numbers and a range of values greater than...
The range of a function is the possible values for y the function can result in after operating the function. However, in a piecewise-defined function, we would need to examine the values for y when both evaluating and graphing the function. Take a look at the graph for the example we ...
Sometimes, data is modeled by two or more equations, each with its own domain restriction. When these equations are written in function notation, such functions are called piecewise-defined functions.The equations making up a piecewise-defined functions may be linear or nonlinear. Actually, you ...
Domain & Range: The domain and range of the piecewise function can be the same as the defined domain and range of all the functions. Also, in order to plot the graph, we need to know the domain and the range of that function. Answer and Explanation: We have to ...
Piecewise Function:A piecewise function is a group of sub-functions each defined over a certain interval. A piecewise function will look something like this:f(x)={g(x)0≤x≤ah(x)a<x Let's use our understanding of domains and ranges to find the domain and range of 2 p...

A piecewise function also known as conditional function, is a function that is defined on a set of intervals. It is a function that has many pieces. To graph a piecewise function we must take care of the domain and range ...
Piecewise functions consist of different function rules for different parts of the domain. 2x + 1 if x ≤ 2 x 2 – 4 if x > 2 h(x) = h(–1) = 2(–1) + 1 = –1 h(4) = 4 2 – 4 = 12 Evaluate each piecewise function for x = –1 and x = 4. To evaluate any piece...
