1. Find f'(x) of each of the following functions
x²e¬x
f (x) =
x+1
• f(x) =
2x+1
x²+3 '
f(x) = In.
f (x) = ex* In(x³).
2. Suppose you are running a factory, producing some sort of widget that requires steel as a raw
material. Your costs are predominantly human labor, which is $ 20 dollar per hour for your
workers, and the steel itself, which runs for $170 dollar per ton. Suppose your revenue R is
loosely modeled by the following equation:
'x+1
R(h, s)
= 200 200hs/3
h represents hours of labor
s represents tons of steel
If your budget $ 20000 dollar, what is the maximum possible revenue?
