f(3) = …?
Nt : blh req
Q.(2/5)
Penjelasan dengan langkah-langkah:
f(x) = x! – 6x + (30 × 2x)
f(3) = 3! – 6(3) + (30 × 2(3))
f(3) = (3.2.1) – 18 + (30 × 6)
f(3) = 6 – 18 + 180
f(3) = -12 + 180
f(3) = 168
Jawaban ⤵
f(x) = x! – 6x + 30 × 2x
f(3) = 3! – 6(3) + 30 × 2(3)
f(3) = ( 3 × 2 × 1 ) – ( 6 × 3 ) + 30 × ( 2 × 3 )
f(3) = ( 6 × 1 ) – ( 6 × 3 ) + 30 × ( 2 × 3 )
f(3) = 6 – ( 6 × 3 ) + 30 × ( 2 × 3 )
f(3) = 6 – 18 + 30 × ( 2 × 3 )
f(3) = 6 – 18 + 30 × 6
f(3) = 6 – 18 + 180
f(3) = -12 + 180
f(3) = 180 – 12
f(3) = 168 ✓
