# Find the Derivative of the Following Function at the Indicated Point: - Mathematics

Find the derivative of the following function at the indicated point:

#### Solution

x at x = 1

$\left( ii \right) \hspace{0.167em}\text{ We have }:$
$f'(x) = \lim_{h \to 0} \frac{f(1 + h) - f(1)}{h}$
$= \lim_{h \to 0} \frac{1 + h - 1}{h}$
$= \lim_{h \to 0} 1$
$= 1$
