2. Press , , , ,
3. Press
4. You will see a menu with three options:
i. Start This tells the calculator what input to
start with. It is set to start with an input of
zero.
ii. Step This tells the calculator how much you
want each input to go up by. It is set at one,
which means the inputs will be consecutive
and go up by 1.
iii. Auto or Ask-x – Auto tells the calculator

TO ENTER A FUNCTION RULE AND PLAY THE FUNCTION
GAME USING THE CALCULATOR
Let’s imagine Stanley and Stella are going to be playing the function game using
a TI-30XS.
Stella would begin by entering a function rule into the calculator. As an example,
she would follow these steps to enter the function rule In + 6.
1. Press
2. Press , ,
3. On the options menu, she would choose Ask-x . Choosing Ask-x tells the
calculator you want to enter the inputs in manually, one at a time.
4. Then Stella would press .
5. At this point, Stella should see a blank in-out function table.
6. Next, Stella would give the calculator to her partner, Stanley.
7. Stanley can enter an input into the function by pressing any number and then
. The calculator will use the function entered in steps 1-3 and display
the output.
8. Stanley can continue entering inputs until he thinks he knows Stella’s
function rule and can successfully predict the output for any input.
9. Stanley would then confirm with his partner Stella that he has correctly
figured out her function rule and they can switch roles.
