Answer:</h2>
Option: B. is the correct answer.
B. ![f(x)=3x+26\ ;\ 26\leq y\leq 35](https://tex.z-dn.net/?f=f%28x%29%3D3x%2B26%5C%20%3B%5C%2026%5Cleq%20y%5Cleq%2035)

Step-by-step explanation:</h2>
It is given that:
A-mowing company is trying to grow its business. It had 26 clients when they started.
It had 26 clients when they started its business and wants to increase by 3 new clients each week.
i.e. if x represents the number of week, then the function which represents the number of clients is:
![f(x)=3x+26](https://tex.z-dn.net/?f=f%28x%29%3D3x%2B26)
( Also, the range of the function is the set of all the values which are attained by a function in it's domain)
We are asked to find the range of the function for the first four weeks of data.
i.e. when x=0,1,2 and 3
i.e. x=0 is the initial week i.e. the first week when it was started.
x=1 is the second week after the start and so on.
Hence, we have:
the range as: ![26\leq y\leq 35](https://tex.z-dn.net/?f=26%5Cleq%20y%5Cleq%2035)
