The dimensions of the base of Box 1 are x by 3x. The base area of Box 1 is:
3x
3x^2
3x^3
4x

3x^2

Step-by-step explanation:

x * x  = x^2

3 * x^2 = 3x^2

  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).

step-by-step explanation:

i think you should think about the question and not look online.
