## Question:

(1) Find the derivative of {eq}f(x)=\frac{5}{3x+5} {/eq} using the limit definition of derivative. (2) Find the derivative of {eq}f(x)=\sqrt{3x+5} {/eq} using the limit definition of derivative.

## Differentiation by the Limit Derivative Method:

{eq}\displaystyle \text{We can find any derivative by using the limit definition of a derivative.}\\[10pt] \text{This is the process of finding the derivative of function f(x) by using the following definition}\\[10pt] f'(x)=\lim_{h\to0} \frac{f(x+h)-f(x)}{h}\\ {/eq}

.

we can apply the limit definition of a derivative to differentiate this function:

{eq}\displaystyle{\text{Let}f(x)=\frac{5}{3x+5}\\[10pt] \text{Then...
