 Polynomial – A monomial or a sum of monomials

The standard form of a polynomial lists the terms in descending order of degree

Menu > 4 > 1 > 3 - Performs linear regression Home > Opens a graphing window Menu > 3 > 4 - Scatterplot Select x for x and y for y - Data for scatterplot Menu > 4 > A - Window to fit data

Menu > 3 > 1 - Function Graph Select f1(x) - Displays the linear regression

Cntrl > Left - Return to data Menu > 4 > 1 > 6 - Performs Quadratic Regression Select x for x and y for y, save to f2 Return to graphing window and activate f2(x) Which model is better, linear or quadratic?

Return to the data one more time This time, select Cubic model and save as f3(x) Can we do better than Cubic?

 Relative Maximum, Relative Minimum – The greatest or least y-value among nearby points on a graph

 Polynomial zeros– The factored form of a polynomial can help find the zeros of the function graph

Enter this into a new graphing page on the calculator

To view data points, Menu > 2 > 9 Move up and down to see the zeros Trace also finds zeros

 Multiple Zeros– A polynomial that has more than one zero at the same x value  Multiplicity – The number of times a zero occurs at the same value
