How do I use the limit definition of derivative to find f ' (x) for f (x) = mx + b ? Remember that the limit definition of the derivative goes like this: f '(x) = lim h→0 f (x + h) − f (x) h. So, for the posted function, we have. f '(x) = lim h→0 m(x + h) + b − [mx +b] h. By multiplying out the numerator, = lim h→0 mx + mh + b − mx ...
The following problems require the use of the limit definition of a derivative, which is given by They range in difficulty from easy to somewhat challenging. If you are going to try these problems before looking at the solutions, you can avoid common mistakes by making proper use of functional notation and careful use of basic algebra.
