-409

Step-by-step explanation:

At the beginning - 12,135 subsribers,

Initial number of subsribers = 12,135

At the end - 10,090 subsribers

Final number of subsribers = 10,090

Time = 5 years.

So, the average yearly rate of change is

$\dfrac{\text{Final number of subsribers}-\text{Initial number of subsribers}}{\text{Time}}\\ \\=\dfrac{10,090-12,135}{5}\\ \\=\dfrac{-2,045}{5}\\ \\=-409$

The number of subscribers decreases by 409 per year

The graph of the given exponential function $\rm f(x) = 3^x$ is attached below and this can be determined by using the given data.

Given :

$\rm f(x) = 3^x$

The following steps can be used in order to determine the correct choice that matches the graph you drew:

Step 1 - Write the given exponential function.

$\rm f(x) = 3^x$

Step 2 - The domain of the function $\rm f(x) = 3^x$ is $(-\infty,\infty)$ .

Step 3 - The range of the function $\rm f(x) = 3^x$ is $(0,\infty)$ .

Therefore, the correct option is B) and the graph of the function $\rm f(x) = 3^x$ is attached below.
