Find the absolute maximum and minimum of the function f(x, y, z) = yz + xy subject to the constraints y^2 + z^2 and xy = 6.
See attached file for full problem description.
Max value is 66.5
Min value is -54.5
Since xy=6 is a constraint, we have ...
This shows through a brief, stepwise explanation how to find the maximum and minimum values of a function.
