Q. f(x) = 9x² + 25 × x!! ÷ 2 f(8) =

Q.
f(x) = 9x² + 25 × x!! ÷ 2
f(8) =

f(x) = 9x² + 25 × x!! ÷ 2

f(8) = 9(8²) + 25 × 8!! ÷ 2

f(8) = 9(8 × 8) + 25 × (8 × 6 × 4 × 2) ÷ 2

f(8) = 9(64) + 25 × ( 48 × 8) ÷ 2

f(8) = 576 + 25 × 384 ÷ 2

f(8) = 576 + 25 × 192

f(8) = 576 + 4.800

f(8) = 5.376

SOAL 1

f(x) = 9x² + 25 × x!! ÷ 2

f(8) = 9(8²) + 25 × 8!! ÷ 2

f(8) = 9(64) + 25 × (8.6.4.2) ÷ 2

f(8) = (9.64) + 25 × (48.4.2) ÷ 2

f(8) = 576 + 25 × (192.2) ÷ 2

f(8) = 576 + 25 × 384 ÷ 2

f(8) = 576 + 25 × 192

f(8) = 576 + 4.800

f(8) = 5.376
