Either table a or table b shows a proportional relationship. table a: x −2 −1 0 1 y 2 3 0 5 table b: x −1 0 1 2 y −3 0 3 6nvm you dont have to answer this i just found out the answer

Table B Shows proportional relationship.

Step-by-step explanation:

Correct answers are the green and yellow dots. Hope this helps. The red dot I got wrong.

  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).
