Let $f(x)=2x^2.$ Compute $f(3A).$

$($Use symbolic notation and fractions where needed$)$

$f(3k)=$

Compute $\frac{\text{N}\text{a}\text{t}\text{y}-NB}{3}.$

$($Use rymbolic notation and fisctions where necolod.$)$

$\frac{f(3k)-f(3)}{k}$

Conspole $f^{\text{'}}(3)$ by taking the limit as $h-0.$

$($Cive your answer as a whole or east number$)$

$(3)=$
