level of utilityŪ. Assume that E = p₁x₁ + p₂x²; Ū=x^x^; and p₁ and p₂ are given.
a) Set up the Lagrangian.
b) Show the first-order conditions or minimization.
c) Derive the expressions for the optimal levels of x, and x₂.
d) Using the second-order conditions, verify if the solution generates a minimum value
for E (Use H₂ to verify).
