Nessa seção, exploraremos as possibilidades de operações e composição com funções
Considere as f(x) e g(x). É possível realizar operações com essas funções:[br][br][table][tr][td][b]Operação [/b][/td][td][b]Entrada[/b][/td][/tr][tr][td][math]h\left(x\right)=f\left(x\right)+g\left(x\right)[/math][/td][td]h(x)=f(x)+g(x)[/td][/tr][tr][td][math]\text{h(x)=f(x) \cdot g(x)[br]}[/math][/td][td]h(x)=f(x)*(x)[br][/td][/tr][tr][td][math]h\left(x\right)=\frac{f\left(x\right)}{g\left(x\right)}[/math][/td][td]h(x)=f(x)/g(x)[/td][/tr][tr][td][math]h\left(x\right)=f\left(x\right)^{g\left(x\right)}[/math][/td][td]h(x)=f(x)^g(x)[/td][/tr][/table]
Sendo [math]f\left(x\right)=x^2[/math], [math]g\left(x\right)=x^3[/math] e [math]h\left(x\right)=\frac{f\left(x\right)}{g\left(x\right)}[/math], construa a função h(x).
Através do GeoGebra, é possível obter a solução de equações lineares.
