Write a formula for the piecewise function graphed below.

The piecewise function is defined by three horizontal linear equations:
A piecewise function is a function formed by two or more expressions constrained by intervals, In this problem we find a piecewise function formed by three horizontal linear equations with three intervals. Horizontal linear equations are zero order polynomials of the form y = a. Therefore, the definition of the piecewise function according to the graph is shown below:
