<h2>Hello!</h2>

The answer is:

The correct option is the second option:

$\frac{5}{2},\frac{-1}{2}$

We are given the following expression:

$\frac{2+-\sqrt{9}}{2}$

Now, solving we have:

First solution:

$\frac{2+\sqrt{9}}{2}=\frac{2+3}{3}=\frac{5}{2}$

Second solution:

$\frac{2-\sqrt{9}}{2}=\frac{2-3}{3}=\frac{-1}{2}$

Hence, we have that the correct option is the second option:

$\frac{5}{2},\frac{-1}{2}$

Have a nice day!

For f(x)=0.01(2)power of x, find the average rate of change from x=3 to x=8

sineoko [7]

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\
of\ change
\end{array}\\\\
-------------------------------\\\\
f(x)= 0.01(2)^x \qquad 
\begin{cases}
x_1=3\\
x_2=8
\end{cases}\implies \cfrac{f(8)-f(3)}{8-3}
\\\\\\
\cfrac{0.01(2)^8-0.01(2)^3}{8-3}$
