Question

About the Lagrangian method, select the correct statement: We can use it to solve consumer's utility maximization problems, but not firm's cost minimization problems. We can use it to solve both consumer's utility maximization and firm's cost minimization problems. We can use it to solve firm's cost minimization problems, but not consumer's utility maximization problems. We cannot use it to solve any kind of optimization problem.

Answer 1

Answer:

About the Lagrangian method,

We can use it to solve both consumer's utility maximization and firm's cost minimization problems.

Explanation:

Lagrangian method is a mathematical strategy for finding the maxima and the minima of a function subject to equality constraints.  Equality constraints mean that one or more equations have to be satisfied exactly by the chosen values of the variables.  Named after the mathematician, Joseph-Louis Lagrange, the basic idea behind the Lagrangian method is to convert a constrained problem into a Lagrangian function.
