When x is less than -2, the definition is:

When x is between -2 and 3, inclusive, the function is:

When x is greater than 3, the definition is:

The graphic is given by the image at the end here, with the closed circle indicating the inclusive on the intervals.

Step-by-step explanation:
Approach: If four numbers a, b, c and d are in proportion then a:b = c:d.
