A radioactive substance of decaying so that the number of grams present after T days is given by the following function: A(t) = 450e ^ -0.04 t

question 1: How many grams are left after 8 days? (round to the nearest whole gram)

question 2: how long until 75 grams are left? (round to the nearest day)

  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).

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !
