We use piecewise functions to describe situations in which a rule or relationship changes as the input value crosses certain “boundaries.” For example, we often encounter situations in business for which the cost per piece of a certain item is discounted once the number ordered exceeds a certain value.

Why is piecewise function important in real life?
A simple example of the need for piecewise functions occurs when you lease a car. To lease a car is to essentially rent the car for a period of time. You lease a car for four years for with a mile limit of miles. This limit means that if you drive more than miles, you will have to pay a fee.
What is the purpose of using piecewise functions quizlet?
Piecewise functions can be used to accurately represent real-world problems because there are some problems, that have multiple interpretations and multiple answers to show.
What is the significance of the piecewise functions in discontinuous functions?
There are two types of discontinuous functions. There are piecewise functions and functions that are discontinuous at a point. A piecewise function is a function defined by different functions for each part of the domain of the entire function (sometimes referred to as "the support," indicating the x axis in 2D).
How do you know which piecewise function to use?
Evaluating piecewise function
To evaluate a piecewise function at any given input, First, see which of the given intervals (or inequalities) the given input belongs. Then just replace the given input in the function definition corresponding to that particular interval.
