1. 2-2: Piecewise Functions Unit 2: Linear Functions English Casbarro

2. Piecewise Functions  Piecewise functions have different range values depending on the domain values that are used.  For instance, a movie theater could charge $5.00 for all children 12 and under, $9.00 for everyone between 13 and 55, and give a senior citizen discount price of $6.50 to everyone 55 and over.

3. The graph of such a function would look like this: The table of values would look like this: So, depending on your age, the Price of your ticket would vary.

4. This is the equation for the example you just saw. This is a step function, since the range is all constant values.

6. Create a table of values and a verbal description of the following graph.

7. A step function has a constant value for each member of the domain. Not all piecewise functions are constants, but there is one that you should know. The greatest integer function is denoted by [x] and is graphed as the greatest integer not greater than the number shown.

8. A truck driver earns $21.00 per hour for the first 40 hours of work per week. The driver earns time-and-a-half, or $31.50 for each hour of overtime. The pay that the driver will earn can be shown by the function below. Example 3 There are 2 different equations that you would graph, depending on the domain values used.

11. Graph each of the following functions.
