Consider the following constrained nonlinear optimization problem: Maximize (x, y) = (x - 3)2 + (y - 3)2 Subject to x + 2y = 4

Consider the following constrained nonlinear optimization problem:

Maximize ƒ(x, y) = (x - 3)2 + (y - 3)2

Subject to

x + 2y = 4

(a) Use a graphical approach to estimate the solution.

(b) Use a package or software library (for example, Excel) to obtain a more accurate estimate.
