8. In mathematics, you can create something called a piece-wise function. This is a graph that is made
up of several functions at one time. Each function is only defined within a certain interval. You know
this interval as a function's domain. For programming purposes, another way that you can write the
interval (-3, 4] is-3 < x≤4. Using the piece-wise graph below, see if you can identify the three
functions and their domains.
