You can enter up to three named functions that allow you to create composite functions. The three named functions are f(x), g(x) and h(x).
To define a function, enter it on one line. For example, you could type.
f(x) = x2+1
to define the function f(x) = x2 + 1
Once a function has been defined, it can be used on subsequent lines.
If you define multiple named functions, you can create composite functions. Note that FX Draw/Graph does not support the fog(x) style of entering composite functions.
