Lesson Summary:

In this lesson, you will learn how to compute the numerical value of the derivative of any function at a given input using a calculator. You'll be able to handle complicated algebraic questions by inputting the functions into the calculator and evaluating them at a particular input value. This video covers the derivative of a sum, product, quotient, and composition of functions. The lesson provides an example problem of how to take the derivative of sales functions, and it shows how to add or subtract them to find the total rate of change of both functions combined.

Lesson Description:

Be able to compute the numerical value of the derivative of ANY function at a given input including a function constructed from a sum, difference, product, quotient or composition of functions.
