Problem:
Given the function

graph the functions f(x - A)
for  A = -2, -1, 0, 1, 2 
using the TI-85 graphing calculator.

- 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.
- 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.
- Press the GRAPH key and then pick y(x)=
by pressing the F1 key.
- If necessary, keep pressing F4 key until only
y1= appears on the screen.
- Type in
2nd x2(1 - (x - A))
and press the ENTER key.
IMPORTANT: A must be upper case.
- The range settings for the graph above is  [-4, 4] × [-3, 3].
- Note that the graphs of the functions are plotted in the order in which
the values are stored in A.
