What are basic functions?
The basic polynomial functions are: f(x)=c, f(x)=x, f(x)=x2, and f(x)=x3.
The basic nonpolynomial functions are: f(x)=|x|, f(x)=√x, and f(x)=1x.
A function whose definition changes depending on the value in the domain is called a piecewise function.
The value in the domain determines the appropriate definition to use..
