For this case, the first thing to do is to observe the value that the function takes on the axis y, when on the x axis we have 30 students.
We have then:
For x = 30:
The value of y is given by:
y = 175 (approximately)
Answer:
y = 175 subscriptions
Step-by-step explanation:
We want to graph:
![f(x) =\log_{5}(x - 3)](https://tex.z-dn.net/?f=f%28x%29%20%3D%5Clog_%7B5%7D%28x%20-%203%29%20)
We first graph the parent function
![g(x) =\log_{5}(x)](https://tex.z-dn.net/?f=g%28x%29%20%3D%5Clog_%7B5%7D%28x%29%20)
This parent function has x-intercept at (1,0) and it is asymptotic to the y-axis.
We then shift the graph of the parent function 3 units right, to obtain the graph of
![f(x) =\log_{5}(x - 3)](https://tex.z-dn.net/?f=f%28x%29%20%3D%5Clog_%7B5%7D%28x%20-%203%29%20)
The new x-intercept will be (4,0) and vertical asymptote will now be x=3.

Its 4 by the way cause it is
B and D because the domain is the set of X coordinates. (x, y) x is your domain.
You purchase 4 videos
The original price of each video is x dollars
You decide to purchase the limited edition versions of the videos for an additional cost
Your total cost is (4x + 20) dollars
So, total additional cost is $20
since, we are purchasing 4 videos
so, additional cost in each videos is
![=\frac{20}{4}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B20%7D%7B4%7D)
![=5](https://tex.z-dn.net/?f=%3D5)
So, limited edition cost additional $5 per videos.........Answer
