Answer:Rate of change is 7
Option B is correct.
Step-by-step explanation:
We need to find the average rate of change for from x = 4 to x = 6
The formula used to find average rate of change is:
Where b = 6 and x = 4
Finding f(6):
Finding f(4):
Now Putting values:
So, Rate of change is 7
Option B is correct.

Answer:
1.
2.
3. The first one represents Dale's commission
Explanation:
1. The composition of the function
means that you first apply the function g(x) and then f(x) on the output of g(x).
That is:
2. The composition of the function
means that you first apply the function f(x) and then g(x) on the output of f(x).
That is:
3. Which one represents Dale's commission
To calculate Dales's commision you must subtract $3,000 from the sales, to find the sales over $3000. That is: x - 3,000, which is the function g(x).
Therefore, you first use g(x).
Then, you must multiply the output of g(x) by 0.05 to find the 5% of the sales over $3,000. That is: 0.05(g((x)) = 0.05(x - 3000) = 0.05x - 150.
Therefore, the composition that represents Dale's commission is the first one:
