Which of the following is(are) the solution(s) to 7 | X+21= -49 ?

A. All values are solutions
B. No Solution
x = 5,-9
D. x=-5,9

  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).

answer:

your answer is: c. 196 7/8 in^3.

i believe it's a.

i'm not sure on this one, most likely correct.
