ada yg mau ?_.

Penjelasan dengan langkah-langkah:

f(x) = 78x² - x!!

f(10) = 78(10²) - 10!!

f(10) = 78(100) - (10.8.6.4.2)

f(10) = 7800 - (80.24.2)

f(10) = 7800 - (80.48)

f(10) = 7800 - 3840

f(10) = 3.960

Jawaban:

$f(x) = \bold{ 78x {}^{2} - x!!}$

$f(10) =$

$\bold{penyelesaian}$

$f(10) = \bold{78(10 {}^{2} ) - 10!!}$

$f(10) = \bold{78(10 \times 10) - (10 \times 8 \times 6 \times 4 \times 2)}$

$f(10) = \bold{(78 \times 100) - (80 \times 6 \times 4 \times 2)}$

$f(10) = \bold{7.800 - (480 \times 4 \times 2)}$

$f(10) = \bold{7.800 - (1.920 \times 2)}$

$f(10) = \bold{7.800 - 3.840}$

$f(10) = \underline{\bold {3.960}}$
