10. You can model the population of a Florida town between the years 1980 and 2015 by the function f(x) = 90,000(x – 1960), where x is the year. In what year did the town have a
population of 450,000?

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

because they could drop even lower..

the answer is y = 11.54

hope this : )

just sum

10 + 10 = 20
