The following examples illustrate the associative property of addition.
(5 + 2) + 3 = 5 + (2 + 3)
3.5 + (1.2 + 9.6) = (3.5 + 1.2) + 9.6
Study the examples, then choose the statement that best describes the property.

a + (b + c) = (a + b) + c

Step-by-step explanation:

a + (b + c) = (a + b) + c

  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).
