Answer: B

Step-by-step explanation:

The initial number of cell phone users is the front coefficient that is then multiplied by the growth factor.

So the initial number of cell phone users in 2000 was 1125.

The correct choice is B, that is, there were 1125 cell phone users in 2000.

Analyzing a power function in a single choice question

In this question we should choose one correct choice associated with a power function that approximates the number of cell phone users. After a quick inspection to the function, we see that rate of growth is 3.4 % and there are the following quantities in 2000 and 2005, respectively:

[tex]x = 0[/tex]

[tex]y = 1125\cdot (1.034)^{0}[/tex]

[tex]y = 1125[/tex]

[tex]x = 5[/tex]

[tex]y = 1125*1.034^{5}[/tex]

[tex]y = 1329[/tex]

Hence, the correct choice is B, that is, there were 1125 cell phone users in 2000. [tex]\blacksquare[/tex]
