Function Entry

Previous  Top  Next

FX Graph uses the equation engine from FX Equation so entering functions is extremely easy AND you can see a fully formatted version of your function as you type.

Functions are entered into FX Graph by typing what you see WITHOUT any formatting. On most occasions FX Graph will automatically format your function for you.

For example. If you want to graph the function 3x³ + 2x² - 7 simply enter 3x3+2x2-7 into the function entry area. FX Graph automatically recognises and formats the powers and displays the formatted function for you to check your entry.
Simple fractions are also entered as you see them. In other words if you want to graph

you enter 3x3/2x4 and FX Graph will automatically build the appropriate fraction. Most simple functions can be entered this way, with NO formatting on your part. More complicated functions will require some limited extra input on your part.
