Find the derivatives of the functions at the indicated points x at x = 1

Given:

f (x) = x

By using the derivative formula,

derivative of x at x = 1 is given as 

\( f(x)=\lim\limits_{h\to 0}\dfrac{(1+h)-1}{h}\)

\( f(x)=\lim\limits_{h\to 0}\dfrac{h}{h}\)

\( f(x)=\lim\limits_{h\to 0}=1\)

derivative off (x) = x at x = 1 is 1
