8. Čonsider the function f (x, y, z) = x°y + e9². (a) f subject to the constraint x2 + y? = z² + 1. Call this System A. Do NOT attempt to solve your system. Use Lagrange multipliers to write out a system of equations to solve for optimizing Do the same thing for f subject to the constraint 3x2 + 2y² + z² = 1. Call this (b) System B. Again, do NOT attempt to solve your system. Systems of n equations with n variables don't always have solutions, but in this case we can guarantee that one of the systems you’ve written above must have a solution. Which is it and why? Hints: What points are your systems trying to find? What theorems do we have related to finding such points?
