Piecewise function
function which is defined by multiple sub-functions each over its own interval
In mathematics, a piecewise function is a function that is defined using multiple rules. Each rule specifies the function values for a portion of the domain, and the rules are conjoined together using the symbol.[1] For example, there might be a function which gives when , and when .
The absolute value function, floor function and step function are some common functions which are usually defined piecewise.[2][3]
