1-22.

This piecewise function has five steps (or pieces). Look closely at the Boundary Points between pieces: *x* = 1 oz, *x* = 2 oz, *x* = 3 oz, *x* = 4 oz, etc. Will you pay a higher or lower rate if your item weighed exactly any of those amounts?

Notice that this piecewise function consists of five horizontal pieces. Recall that a horizontal line is of the form *y* = *k*, where *k* is a constant. Also, consider the boundary points: will ≤ or ≥ be appropriate?
