Earl's Electronics stocks iPhones and Androids at a ratio of 9:4. Which combination of iPhones and Androids could they carry? A. 81 iPhones and 36 Androids

B. 72 Androids and 32 iPhones

C. 45 iPhones and 25 Androids

  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).
