# Derivative as a Function Example 2: y = x^3 - x

in MES Science6 days ago

In this video I go over another example to better illustrate the derivative as a function as well as in implementing the definition of the derivative. The example I go over is finding the derivative of the function y = x3 - x.

# Derivative as a Function: Example 2

## Example 2

(a) If f(x) = x3 – x, find a formula for f’(x) using the definition of a derivative.

(b) Illustrate by comparing the graphs of **f **and f’.
