genapin poin sekali lagi :v

f(x) = 3x² + 9x
f'(x) = ?

|><> Penyelesaian <><|

f(x) = 3x² + 9x

f'(x) = 2(3)x^(2 – 1) + 1(9)^(1 – 1)

f'(x) = 6x¹ + 9x⁰

f'(x) = 6x + 9(1)

f'(x) = 6x + 9

$purple{boxed{blue{boxed{green{star{pink{ : : mathcal{CG} : : : {green{star}}}}}}}}}$

$f(x) = {3x}^{2} + 9x$

$f(x) = 3 {x}^{2} + 9x^{1}$

$frac{df(x)}{dx} = 3.2x^{2 - 1} + 9.1x^{1 - 1}$

$frac{df(x)}{dx} = 6x^{1} + 9x^{0}$

$displaystyle red{frac{df(x)}{dx} = 6x + 9}$

Note:

Turunan pertama dari ax adalah a
