Operations:   Graphing a Piecewise Function

         It is possible to graph a function over a specific interval within the chosen window.

1. Press Y= and enter the desired function in parentheses.                          For example:
2. Press the ( button again.
3. Press the "x,T,0,n" key
4. Press 2nd-MATH, (TEST)
5. Choose an inequality.  Try > for this example by pressing 3.
6. Enter the value that is the end point of the interval, say -4 and close the parentheses.
7. Graph in a standard window:  It may be easier to see the graph in DOT MODE.
   
   
   
   If the given domain is, for another example,    - 2 < x < 7,  follow these steps.
8. Follow steps 1-5 above to see this:  
9. Press 2nd-MATH
10. Use the right arrow key to highlight LOGIC
11. Because this is a "between" inequality, choose AND  by pressing 1.
    
    
    
     
    
12.   Now  enter the rest of the inequality,
      the x < 7 part: 
13.   Close the parentheses
14.   Press GRAPH                          
    This graph was made in DOT MODE.
    
    
    HINT:  To do a domain with   x< -4 , x > 6  use OR instead of AND.
