![]() The function might have different pieces for different time periods, with each piece representing a different speed. The function might have different pieces for different time periods, with each piece representing a different price trend.Ī piecewise function could be used to model the speed of a vehicle as a function of time. The function might have different pieces for different temperature ranges, with each piece representing a different resistance coefficient.Ī piecewise function could be used to model the price of a commodity, such as oil, as a function of time. The function might have different pieces for different concentrations of the substance, with each piece representing a different rate of dissolution.Ī piecewise function could be used to model the resistance of a material as a function of temperature. For example, the cost per unit might be lower for larger quantities due to economies of scale.Ī piecewise function could be used to model the rate at which a substance dissolves in a solution. ![]() The function might have different pieces for different ranges of production, with each piece representing a different cost structure. Real world examples of Graphing Piecewise Functions A company might use a piecewise function to model the cost of producing a certain product as the number of units produced increases. Other related topics might include the study of continuous and discontinuous functions, or the use of piecewise functions in fields such as engineering and economics. Some related topics to graphing piecewise functions include analyzing and interpreting functions, finding key features such as intercepts and asymptotes, and using functions to model real-world situations. Graphing piecewise functions is typically covered in a precalculus or calculus course. It allows us to see how the function changes as we move from one piece to another, which can be helpful in understanding the overall shape and behavior of the function. Graphing piecewise functions is a useful tool for visualizing functions that have different behavior over different values of x. These pieces are typically defined by x values within a certain range. In Summary Graphing piecewise functions involves plotting a function that is defined by multiple pieces, each with its own function rule. This idea is better illustrated in the following example.See Related Pages\(\) \(\bullet\text\) ![]() 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. 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. In the first region, \(x \ge 3\text\) as shown in Figure144.
