For the function f(x,y) = 4xy - x^3 - 2y^2 find and label any
relative extrema or saddle points. Use the D test to classify. Give
your answers in (x,y,z) form. Use factions, not decimals.
f(x) = 10/cos-1(x). Use calculus to determine:
a) all critical values
b) any local extrema
c) any absolute extrema
d) the intervals where f is increasing/decreasing
e) any points of inflection rounded to the thousandths place
f) intervals where f is concave up/down
No interval was specified so I assumed 0<x<2pi
also I didn't get any concavity not sure if I'm right or
not.
I got x= pi as the critical value as well as the relative and
absolute minimum...
f(x) = −x^3 − 3x^2 + 9x + 12
A) use second derivative test to test for relative max/min
B) Find (x,y) coordinates of point(s) of inflection
C) Define the intervals of concavity
solve by determinants
a.x+y+z=0
3x-y+2z=-1
2x+3y+3z=-5
b. x+2z=1
2x-3y=3
y+z=1
c. x+y+z=10
3x-y=0
3y-2z=-3
d. -8x+5z=-19
-7x+5y=4
-2y+3z=3
e. -x+2y+z-5=0
3x-y-z+7=0
-2x+4y+2z-10=0
f. 1/x+1/y+1/z=12
4/x-3/y=0
2/y-1/z=3
2. For the curve y = 3x / x^2-1 determine each of the following
and use all of the information to draw its graph
and notate the information on it.
(a) Find the domain of the function, as well as any x or y
intercepts and symmetry.
(b) Find all vertical (2 of them) and horizontal (1) asymptotes.
Support your work with limits.
(c) Use the first derivative to determine the maximums, minimums
and intervals of increase/decrease of f(x).
(d)...
