Definition The derivative of a function f is another function f ’ (read “f prime”) whose value at any number x is : Provided that this limit exists and is not or - ØIf this limit does exist f differentiable at c ØOther way if f differentiable at x 1 then f ‘(x 1) exist ØIf a function differentiable at every riil number in their domain then f called differentiable function
Soo if x 1 belong to domain then
Add Note : If we take then
Differentiability Implies Continiuty Ex. Check if continue at x=0 and differentiable at x=0?

Exercise 1 Suppose f with Find a and b such as f continue at x=0 but f’(0) does’nt exist
Exercise 2 Check if the function differentiable at 0 ? ?
Ex 3 Check if the function Differentiable at x=0
Ex 4 Find the derivative from the function :
Ex 5 Calculate d/dx( x ) then show the function y= x satisfied yy’=x, x 0
