Answer:
B
Step-by-step explanation:
From the statement, we are given a function that shows the number of cell tower users f(x) after x years, from the year 2010 to 2019, so, to solve the problem, we need to remember that the domain is equal to all the values that the variable (x for this case) could take making the function itself exist.
So, the given function is a function of years, and we know that "x" represents the years from 2010 (starting value), to 2019 (ending value) meaning that the domain is located between those two values.
Hence, the correct option is:
B. 0 ≤ x ≤ 5,000
Center is ( -1.6 , -9.8 , 0 )
radius = √26 = 5.099 = 5.1
