The graph represents the piecewise

Step-by-step explanation:

We need to find the equation of the straight line on the interval

This line passes through (-1,-3) and has slope 2.

The equation of this line is

On the interval , the function is a straight line.

The straight line passes through; (1,5) and has slope 1.

The equation of this line is

The piece-wise function is;

because they could drop even lower..

squares, rhombus, rectangles
