1. Formulate an application problem that could be modeled mathematically through the graph of the function y=(x²-4x-1)/x Some examples are the cost functions (manufacturing, production, distribution, transportation, installation, setup,etc.), economy charts, population functions, and modeling an epidemic. For further assistance, newspapers, magazines, and news sites are filled with various data and corresponding graphs.
2. Answer the following questions:
   • For what values of the independent variable does the function have a practical interpretation in the context of your application problem? Explain.
   • In Desmos, draw the graph of the first derivative function and interpret it in the context of your application problem.
   • Find all values, for which the first derivative of the function is0 and interpret them in the context of your application problem.
   • In Desmos, draw the graph of the second derivative function and interpret it in the context of your application problem.
   • Find all values, for which the second derivative of the function is0 and interpret them in the context of your application problem.
