Question $1f(x)$ using the definition $of$ the derivative $(Note$: You

may decide which variation $of$ the difference quotient $to$ use$)(4$ points each$)$

Recall the definition $of$ the derivative formulas:

$f^{\text{'}}(a)=\underset{xa}{lim}\frac{f(x)-f(a)}{x-a}$ and $f^{\text{'}}(x)=\underset{h0}{lim}\frac{f(x+h)-f(x)}{h}$

$af(x)=\sqrt[\phantom{2}]{x+3}$
