Here is what the above function should look like if graphed as described above. Pressing the down arrow or QUIT accepts the style. Choose the three distinct dots for dotted style. When the cursor is in this position, pressing enter will cause the indicator to cycle through the possible styles. To change it, place the entry cursor over the formula and use the left arrow key to move over the style indicator. The plotting style is indicated to the extreme left of each formula. To turn this off, choose dotted style for this formula in the Y= menu. Usually, this can be handled from the ZOOM menu by selecting ZDecimal.Īlso, if the "connected" option is turned on for this type of graphing, you will get false information at discontinuities. Isolated points such as (1, 3) in the above example will not be visible unless you insure that the x-coordinate of that point is used by the calculator as a plotted point. Not sure if the 83s can graph piecewise, but it should work, its just basic. It will only graph a Piecewise with 2-4 functions. Allthough, it may make graphing a piecewise function easier for some. Notes:The inequality and equality symbols are found in the TEST menu. Piecewise Funtion grapher this program does basically what most people can do in their Y screen, but takes up more space. General method: The trick to this is knowing that expressions involving,, £,, =, and from the TEST menu are evaluated by the calculator as either 1 or 0 according as the expression is true or false for a given value of x. Graphing Piecewise Functions Using a calculator to create the graph of a piecewise-defined function (TI 83)
