9. Reed, Riley, Ean, and Michael want to run a race against each other. They start on the 20 yard line of the football field and finish at the 50 yard line. The times for them to
complete the race are listed in the table.
Reed
4 seconds
Riley
5 seconds
Ean
6 seconds
Michael
10 seconds
Which of the boys ran the race at an average speed of 5 yards per second?

  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).
