Example 1: (Plot a function) Suppose you wish to plot the function
---------------To plot this function, enter x^3-2x^2-1
---------------in the box below and to the right of Function =.
---------------Click on the Enter your Function button.
---------------x^3-2x^2-1 will appear to the right of Your Input Function is:,
---------------and to the right of The replaced function = f(x) =,
---------------and x^3-2x^2-1 in the box below Function f(x) in the grapher below.
---------------Next click on the Plot Graph button in the grapher below.
---------------This will enter the value -1 to the right of f(x) = in the grapher and
---------------will draw a red curve of the function with a circle on the curve at the point x = 0.
---------------If you type a 1 in the for x = box, and click on the Plot Graph button,
---------------the circle will move to a point on the curve f(1) = -2.
---------------In this way, you can find any value of f(x) for any given x-value
Enter your calculation or function below in the box to the right of Function =.
