The answer is A. f(2) = 2

We are looking for where the line is expressed when x = 2. A closed dot allows us to know that point is included. An open dot is not included, although the line approaches it, infinitely closely.

Answer:

f(2)=2

Step-by-step explanation:

From the graph we need to find f(2)

f(2) is the value of y when x=2

When x=2 , we have two graphs that goes up and goes down

The down graph starts at y=1 but we have a open circle.

the top graph starts at y=2 but we have closed circle.

to find the value of when x=2, consider the graph with closed circle

So when x=2 the value of y is 2

f(2)=2

Answer:

2/7 + (-3/4) + (-2/7) + 4/3

If we look at 2/7 and (-2/7), we can see that both of them combined will get you a result of 0, so let's do that first.

2/7 + (-2/7) = 0

Now we're left with;

(-3/4) + 4/3

Make sure to convert both fractions into having a common denominator,

[They both have a common denominator of 12], so:

(-3/4) = (-9/12)

4/3 = 16/12

Add them:

(-9/12) + 16/12

16/12 - 9/12

= 7/12, which cannot further be simplified.

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

sineoko [7]

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