Write the value of lim(x->c)(f(x)-f(c))/...

Write the value of `lim_(x->c)(f(x)-f(c))/(x-c)`.

Text Solution

Verified by Experts

It is given that f′(c) exist ⇒f is differentiable at x=c
And we know that, if f is differentiable at any point then it must be continuous at that point
∴`lim_(x->c)​f(x)=f(c)`
