Which fraction is halfway between 1/2 and 5/6? a. 2/3 b. 4/3 c.3/5 d.7/12 and another question arrange these numbers from least to greatest: -3/7, -5/6, -3/5, and -7/9 ?

  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).
