1. Suppose a utility function is given by u(x₁, x2) = 2√√x₁ + 4x₂. (a) Specify the equation of the indifference curve through (9,4), and write the equation in the form x₂ = .... (b) Now take the derivative with respect to x₁, and evaluate it at x₁ 9. This = is the slope of the indifference curve, and hence you can determine the MRS. (c) Suppose you know that (9, 4) is a person's optimal consumption, and that the price of good 1 is p₁ = 4. You know that at the optimum the MRS must be equal to the price ratio. Use this insight to determine the price of good 2 and the person's income.

Marginal Rate of Technical Substitution
MRTS reaches a manufacturer when a part of the product is lowered to sustain the manufacturing level when the other part is extended. It is the level of the quantity that is lowered when one extra volume is used, and the output is unchanged.
Preferences and Utility Analysis
Before understanding what is preference and utility analysis, it is very important to understand the terms preference and utility separately.
