In this graphic, you can select a utility function and budget restriction. If you
press "Draw", the corresponding graphic is created and commented.
You can also display the values of the function that result when you solve the constraint for y, and insert it into the utility function and its derivative. You can see either that the maximum is reached at the optimum point or that it results in a boundary solution.
"Clear Graph" reinitializes the graph.
ATTENTION: Machines are stupid. If the graph and the numerical solutions appear absurd, this may be due to the fact that the determined solution of the equation system was established incorrectly, because the numerical algorithm is not converged in an inner solution.
