Question
Find the absolute maximum and minimum values of f(x, y) = x + 8y – 32y + 4 on D: the set of points (x, y) that satisfy x? + y < 16.
Part 1: Critical Points
The critical points of f are:
Σ
• Part 2: Boundary Work
Along the boundary f can be expressed by the one variable function:
f = f(y) =
Σ
List all the points on this side of the boundary which could potentially be the absolute minimum or maximum on D.
Σ
• Part 3: Final Results
Find the function's absolute maximums and minimums and where they occur.
The absolute maximum of f is:
Σ
and it occurs at
Σ
The absolute minimum of f is:
Σ
and it occurs at
Σ
