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. Find the absolute minimum and maximum value of f(x) = x4 −
18x 2 + 7 (in coordinate form) on [-1,4]
2. If f(x) = x3 − 6x 2 − 15x + 3 discuss whether there are any
absolute minima or maxima on the interval (2,∞)
show work please
The function
f(x,y,z)=4x−9y+7z
has an absolute maximum value and absolute minimum value subject
to the constraint
x^2+y^2+z^2=146.
Use Lagrange multipliers to find these values.
