Marta drove 3/4 mile to the grocery store and then another 1/2 mile to her friend's house. If the trip home is 3/4 the length of the total trip to her friend's house, how far did Marta drive on the round trip?

Her speed is 0.2 miles per minute (.2miles/min).

  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).
