The definition of the given piecewise function is:
<h3>What is a piecewise function?</h3>
A piecewise function is a function that has different definitions, depending on the input.
In this problem, for x until 2, the function is the cube function shifted down 3 units, hence the definition is:

For x greater than 2, the function is the square function shifted up 6 units, hence the definition is:
