Which of the following lists of ordered pairs is a function? O A. (2,5), (3,6).(6,9)
O B. (1,2), (4,0), (3,5),(4,3)
O c. (2,5), (3, 6), (2, 1)
OD. (-1,2), (2,3), (3, 1), (2,5)

b

Step-by-step explanation:

  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).
