In that case, the derivative of at equals the equal values. In mathematics, a piecewise-defined function (also called a piecewise function, a hybrid function, or definition by cases) is a function defined by multiple sub-functions, where each sub-function applies to a different interval in the domain. In other words, the values should match, and the values of each of the derivatives up to the derivative should match. This idea is better illustrated in the following example. Consider the function: Then, is times differentiable at if we have all these conditions:, ,. 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.

It can be represented in mathematical form as f (x) 3. For example: If a function takes on any input and gives the output as 3. Comparing Exponential and Linear Growth A function is a mathematical object which associates each input with exactly one output.
