Identifying the general polynomial shape
Example 1General Rule: Basic polynomial function is one more that the number of direction changes.
Example 2
To enter data:
STAT → Edit (Clear any data from lists – arrow up to L1 hit clear – not delete.
Enter x values in L1
Enter f(x) values in L2
2nd STAT PLOT (Plot 1 on. Make sure L1 & L2 being used
Graph (reset window settings, if needed)
Determine # of direction changes (in this case 2)
Stat → Calc → 6 (Cubic regression) OR
Y = → Vars → 5(statistics) → EQ → RegEQ
Verify that graph values are similar to table values.
