Definition The derivative of a function f is another function f ’ (read “f

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
