Move the Slider: [b]Apply function[/b] or Click on [b]Animate[/b] button to see how it changes. This worksheet shows an animated representation of real functions [math]f: D\subseteq \mathbb R\rightarrow R\subseteq \mathbb R[/math]. When the function is applied to any value [math]x\in D[/math], it will determine a number [math]f(x)\in R[/math]. The Domain and Range of [math]f[/math] will be determine by the algebraic expression in the box.
