Jake is riding an escalator. after riding for 3 seconds, he was 25 inches above the ground. a. how many inches is jake rising per second? b. at the rate jake is rising, how many inches above the ground will he be after riding the escalator for 15 seconds? justify your answer. c. the top of the escalator is 30 feet, or 360 inches, above the ground. will jake have reached the top 45 seconds after first getting on the escalator? why or why not?

  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).

step-by-step explanation:

the true ones are a b and d
