Tip
• In the number table shown in step 6, you can change the value in the
currently highlighted x cell. Changing the x value causes the f(x) and g(x)
values in the same line to be updated accordingly.
• If there is value in the x cell above the currently highlighted x cell,
pressing  or  automatically inputs into the highlighted cell the
value equal to the value of the cell above it plus the step value. So also,
