\[\begin{array}{*{20}{l}}
{\begin{array}{*{20}{l}}
{f:}&{\mathbb{R}\backslash \left\{ 0 \right\} \to \mathbb{R}} \\
{}&{x \to \frac{1}{{{x^2}}}}
\end{array}}&{}&{}&{\begin{array}{*{20}{l}}
{g:}&{\mathbb{R}\backslash \left\{ { – 1} \right\} \to \mathbb{R}} \\
{}&{x \to x + 1}
\end{array}}&{}&{}&{\begin{array}{*{20}{l}}
{h:}&{\mathbb{R}\backslash \left\{ {0,1} \right\} \to \mathbb{R}} \\
{}&{x \to \frac{1}{{{x^2} – x}}}
\end{array}}
\end{array}\]
Caracterize as funções seguintes:
\[\begin{array}{*{20}{l}}
{f + g}&{}&{f \times g}&{}&{\frac{f}{g}}&{}&{h – g}&{}&{\frac{f}{h}}&{}&{f \circ g}&{}&{g \circ f}
\end{array}\]
