“Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question”.

A scalar function $f (x, y)$ is a rule that is used to associate a number or quantity with a particular point $(x, y)$ in the plane. In this problem, the multivariable function is $f (x, y) = \frac{x + y}{x - y}$ . We have to sketch the level curves for the function, by selecting three non-zero values of k.
