Is this a function if is not tell why

yes

Step-by-step explanation: all inputs go to one output but they do not go over more than once that is why

  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).

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
