Which of the following is always true of functions?
A) For each value in the range, there
is only one value in the domain.
B) For each value in the domain,
there is only one value in the
range.
C) The range of a function includes
all real numbers.
D) The domain of a function
includes all real numbers.

  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).
