(b) What is the meaning of M 4 in terms of the pollution discharged by the plant?
(c) Suppose that r(t) = 0.5e 0.5t . Use this formula for r to compute L 5 on [0, 4].
(d) Determine an upper bound on the total amount of pollution that can escape
the plant during the pictured four week time period that is accurate within an
error of at most one ton of pollution.
