Find three consecutive even integers such that the sum of the smallest and the largest is 36

Step-by-step explanation: largest=2x+4

their sum =2x+2x+4=36

4x=36-4=32

x=32/4=8

so the numbers are 2*8,2*8+2,2*8+4

that is 16,18,20

  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).
