g(x) = 4x1 + 2x₂ − x3 = -2.
Specify below the value of the Lagrange multiplier, A, and the value of the function f(x*). (Make sure you use g(x) as specified above: if you divide
through by constants, the resulting value of X can change!)
In both cases, give your answer as an exact fraction or a decimal approximation accurate to at least 3 significant figures.
