The number of users of a cell tower in a small, developing town increased by a factor of 1.5 every year from 2010 to 2019. the function below shows the number of cell tower users, f(x), after x years from the year 2010:

f(x) = 5,000(1.5)x

which of the following is a reasonable domain for the function?
2,010 ≤ x ≤ 2,019
0 ≤ x ≤ 5,000
0 ≤ x ≤ 9
all positive integers
show work

Step-by-step explanation:

y=mx+

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
