x represents the independent variable. f(x) outputs the amount of the independent variable at the specied value of x. V(x) = 5 - x outputs the rate of change of the independent variable with respect to x at the specied value of x. The domain of x is partitioned starting at x = 2 and with intervals of length Ax = 0.5 Use this information to answer the following questions. Question 7 1 pts What is the value of x at the start of interval number 5? Question 8 1 pts What is the assumed constant rate for interval number 4? Question 9 1 pts What is the approximate net accumulation for the completed interval number 4? Question 10 1 pts It is known that f(2) = 3.8 Approximate f(3.2)
