Exercise 2

Avg difficulty 2.5

Find the first derivative formula for each of the following functions twice: first by evaluating lim⁡h→0f(x+h)−f(x)h\lim\limits_{h\to0}\frac{\fe{f}{x+h}-\fe{f}{x}}{h} and then by evaluating lim⁡t→xf(t)−f(x)t−x\lim\limits_{t\to x}\frac{\fe{f}{t}-\fe{f}{x}}{t-x}.

f(x)=x\fe{f}{x}=\sqrt{x}
