Function


There are several ways to enter a function into the Casio graphing calculator. For basic use, we recommend simply entering a function into the equation editor and then working with it from there. To begin, press MENU 3 to access the graph table screen. This takes you immediately to the equation editor.

Simply type in the algebraic expression used to define the function. For example, to enter the quadratic function f defined by f(x) = x 2 + 3x - 7, type

X ^ X2 + 3 X - 7 EXE

Once the function is entered, then you can perform a variety of tasks; for example, evaluate the function at a given input value, graph the function, make a table of functional values.
