You can enter up to three named functions that allow you to demonstrate transformations. 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.
