A piecewise function is a function that's simply built from pieces of different functions over several intervals.
<h3>What is a piecewise function?</h3>
Your information is incomplete as the function isn't given. Therefore, an overview will be given. It should be noted that a piecewise function simply means a function that's defined by multiple sub functions.
In this case, each sub-function applies to different interval in the domain as it's way of expressing the function.
