1. Write a function that gives the fee in terms of the number of users. Identify your variables and use your graphing calculator or graph paper to graph the function.

2. Determine the domain and range of the function.

3. Explain the difference between the domain and range of the function and the reasonable domain and range of the problem situation. Justify your answer.

4. Write the equations of the asymptotes?

5. Explain the meaning of the asymptotes in terms of the problem situation.

Part 2:

Which equation best describes the relationship between x and y shown in the table below?
x y –1 –3 1 3 2 1.5 3 1 6 .5

A     
B     
C              
D     

Explanation / Answer

As per date given :

x = -1 ; y =-3

x = 1 ; y =3

x = 2 ; y = 1.5
