3. Press G.
Two graphs are drawn as
shown on the right.
In this case, the first one
represents the equation y =
3x 2 + 5x + 2 and the second y = - 2x 2 + 3x + 4.
You can also use L1 to L6 to enter the equation;
1. Set the lists L1 to L3 as
follows;
{3, - 2}
⇒ L1,
{5, 3} ⇒ L2,
{2, 4} ⇒ L3, and then
2. Enter the equation as follows.
Y1 = L1x 2 + L2x + L3
6. Using L_DATA functions
The calculator can store up to 10 list groups in memory (L_DATA 0 to L_DATA 9). You
may store or recall any one of these list groups. Each list group can contain up to 6
lists.
1 StoLD StoLD natural number (0-9)
Stores the current group of lists (L1 to L6) in L_DATA 0 to 9.
Example
1. Press @ l and
select C 1.
2. Enter the preferred number
from 0 to 9 and press E.
“Done” will appear and the
current lists will be stored in L_DATA #.
