You take the derivative of y with respect to x. You are finding the sensitivity to the change in the function with respect to a change in the argument.

We can abstract the derivative by saying the derivative of the function f (x) = x 2 is 2x. We can also make a generalized definition of the derivative using Zeno’s arrow example: ...
