A firm has identified that total profit P as a function of the number of units of two products manufacturedis given by the following functionP = 12x1 + 32x2 – 2x12– 8x22– 1000where x1 = thousands of units of Product 1 and x2 = thousands of units of Product 2. The number of units ofeach product that can be produced in the next planning period is constrained by the fact that there are only12,000 pound of an ingredient that is used in the production of both products available. Both products requiretwo pounds of the ingredient per unit produced.i) Formulate a mathematical model that can be used to determine how much of each product should bemanufactured in the next planning period so as to maximise profit.ii) Find a solution to your mathematical model.

Consider the function f(x) = x^3 - 4x^2 + 3x + 2. Determine the critical points of this function and classify them as local maxima, local minima, or saddle points. Additionally, find the intervals where the function is concave up and concave down, and identify any inflection points on the graph of f(x).
