Answer: Option d.

Step-by-step explanation:

1. The parent function of an absolute value function is shown below:

f(x)=|x| (This is the simplest form). Because from this function we can make transformations that allow us to obtain the function f(x) = 4|x| -3

2. If you take the parent function and make y= f(x)-3/4, then you have:

y= f(x)-3/4=|x|-3/4 (The function is shifted down 3/4 units on the y-axis).

3. Then you if you make y= 4(f(x)-3/4), as following, you obtain:

y = 4(f(x)-3/4))=4|x|-3 (The function is reflected in the y-axis).

4. That is how you obtain the final function. $f(x) = 4|x|-\frac{3}{4}$

Benny the Barber (see Question 1) is considering the addition of a second chair. Customers would be selected for a haircut on a

Artyom0805 [142]

According to the information presented, Benny should decide not to add a second chair because the average number of clients waiting is 1 (very low), the average waiting time for a client is 10 minutes (very low), and the average time a customer is in the store is 20 minutes (very low).

According to the information, an average of 2 clients arrive at the hairdresser for every hour (60 min) and each cut takes a maximum of 20 minutes. Therefore, the hairdresser would have an average of 40 minutes busy and 20 minutes free for each hour.

Additionally, customers who must wait do not have to spend a long time waiting in the store because the maximum waiting time is 10 minutes (in the case that both customers arrive at the same time).

Below is a graph where the information of both cases is compared (with an additional chair and without an additional chair) and it is inferred that an additional chair is not necessary because the number of clients waiting and the waiting time is not high.
