Quizf(x) = 6x³ + 4x² + 3x + 3maka,f”(x) = ….

Jawaban:

f"(x) = 36x + 8

Penjelasan dengan langkah-langkah:

$f(x) = 6 {x}^{3} + 4 {x}^{2} + 3x + 3$

$f'(x) = 6 times 3 {x}^{3 - 1} + 4 times 2 {x}^{2 - 1} + 3 times 1 {x}^{1 - 1}$

$f '(x) = 6 times 3 {x}^{2} + 4 times 2x + 3 times 1$

$f'(x) = 18 {x}^{2} + 8x + 3$

$f''(x) = 18 times 2 {x}^{2 - 1} + 8 times 1 {x}^{1 - 1}$

$f''(x) = 18 times 2x + 8 times 1$

$f''(x) = 36x + 8$

Jawaban:

$f(x) = 6x^{3} + 4x^{2} + 3x + 3$

$f'(x)=6.3x^{3-1}+4.2x^{2-1}+3.x^{1-1}+0$

$=18x^{2}+8x+3\$

$f''(x)=18.2x^{2-1}+8.x^{1-1}+0$

$f''=36x+8$
