Let f(x)=−14(x+4)2−8 .
nevsk [136]
Answer:
Average rate of change = -112

Explanation:
The average rate of change = \frac{f(b) - f(a)}{b - a}
where:
b is the upper limit = 2
f(b) = f(2) = -14(2+4)² - 8 = -512
a is the lower limit = -2
f(a) = f(-2) = -14(-2+4)² - 8 = -64

Substitute with these values in the above equation to get the average rate of change as follows:
average rate of change = \frac{-512 - (-64)}{2 - (-2)} = -112

Hope this helps :)

\underbrace{3\cdot3\cdot3\cdot\ldots}_{n}\geq900\\\\
3^n\geq900\\\\
\log_3 3^n\geq \log_3900\\\\
n\geq \log_3900\\\\
n\geq\dfrac{\ln 900}{\ln 3}(\approx6.2)

So, the least n is 7.
