Ответ:
a)
is increasing in two regions: (i)
and (ii)
.
b)
decreases in
.
Step-by-step explanation:
Let
, where
is the quantity of insecticide, measured in hundreds of liters, and
is the total manufacturing cost as a function of the quantity of the insecticide, measured in US dollars. A possible approach to determine which regions of
are decreasing and increasing by means of the first derivative and graphing tools. The first derivative of the function is:
Please notice that regions where C(x) is increasing has
, whereas
when
.
We notice that
is increasing in two regions: (i)
and (ii)
. Besides,
decreases in
