Find the absolute maximum and the absolute minimum of
the function f(x,y) = 6 - x² - y² over the region R = {(x,y) | -2
<= x <= 2, -1 <= y <= 1 }. Also mention the points at
which the maximum and minimum will occur.
1. a. Find the relative maximum and minimum values of f(x, y) =
(3x^2) − (2y^2) b. Find the relative maximum and minimum values of
f(x, y) = (x^3) + (y^3) − 6xy . The expression that you may need D
= fxx(x0,
y0)fyy(x0, y0) −
(fxy(x0, y0))2

1. Determine the absolute minimum and maximum values of the
function f(x) = x^3 - 6x^2 + 9x + 1 in the following
intervals:
a) [0,5]
b) [-1,2]
2. A company produces and sells x number of calculators per
week. The functions for demand and cost are the following:
p = 500 - 0.5x and c(x) = 10,000 + 135x.
Determine:
a) Function of weekly revenue
b) Price and number of calculators that have to be sold to
maximize revenue...
1. Find the derivative.
f(x) = x6 ·

2. Find the absolute maximum and
minimum values on the closed interval [-1,8] for the function
below. If a maximum or minimum value does not exist, enter
NONE.
f(x) = 1 − x2/3
3. Find the derivative.
f(x) = x5 ·

Consider the following.
f(x) = -19ln(84x)
Compute f '(x), then find the exact value of
f ' (3).
