  1. If you are not familiar with the graphing of functions on the TI-85, then first read the Initial Setup page from Little's Basic Guide to the TI-85.
  2. Type in
    {-2,-1,0,1,2} STO A

    You can find the symbol { by pressing 2nd LIST and F1; the symbol } is then obtained by pressing F2.

  3. Press the GRAPH key and then pick y(x)= by pressing the F1 key.
  4. If necessary, keep pressing F4 key until only y1= appears on the screen.
  5. Type in
    2nd x2(1 - (x - A))

    and press the ENTER key.
    IMPORTANT: A must be upper case.

  6. The range settings for the graph above is  [-4, 4] × [-3, 3].
  7. Note that the graphs of the functions are plotted in the order in which the values are stored in A.
