Classify the given function as a polynomial function, rational function, or root function, \( h(x)=\frac{2}{x^{2}+36} \)

Translate the sentence into an equation, and solve it. If 8 times a number is decreased by 8 , the result is 48 . Find the number. The equation is (Type an equation using \( x \) as the variable.)

Find the function rule for \( g(x) \). The function \( f(x)=2 x \). The graph of \( g(x) \) is \( f(x) \) vertically stretched by a factor of 4 and reflected in the \( x \)-axis. What is the function rule for \( g(x) \) ? \[ \begin{array}{l}g(x)=-\frac{1}{2} x \\ O_{\text {d }} \\ g(x)=\frac{1}{2} x \\ g(x)=8 x\end{array} \]
