Find the average rate of change of \( f(x)=-2 x^{2}-x \) from \( x=2 \) to \( x=6 \), Simplify your answer as much as possible.

\( \lim _ { m \rightarrow + \infty } \frac { 3 ^ { m } } { \sqrt { 9 ^ { m } + 3 ^ { m } + 3 ^ { n } } } \)

aso a resolver: lecular el área bajo la curva de \( f(x)=3 x^{3}+2 \)

Caso a resolver: Calcular el área bajo la curva de \( f(x)=3 x^{3}+2 \)

\( \lim _ { m \rightarrow + \infty } ( \frac { m ^ { 3 } + 1 } { ( n + 1 ) ^ { 3 } } ) ^ { m } \)

Question 8 Use a calculator to approximate the following to five decimal places. \( \frac{\pi^{e}}{e^{\pi}}=\square \) Submit Question \( \times \) Question 9
