F(x) = 4x × 2x – 10 + 4xf(3) = ..ulang tdi lupa masukin angka nya :v
Jawaban:
f(x) = 4x × 2x – 10 + 4x
f(3) = 4(3) × 2(3) – 10 + 4(3)
f(3) = 12 × 6 – 10 + 12
f(3) = 72 – 10 + 12
f(3) = 62 + 12
f(3) = 74

□ Penyelesaian
f(x) = 4x × 2x – 10 + 4x
f(3) = 4(3) × 2(3) – 10 + 4(3)
f(3) = (4 × 3) × 2(3) – 10 + 4(3)
f(3) = 12 × 2(3) – 10 + 4(3)
f(3) = 12 × (2 × 3) – 10 + 4(3)
f(3) = 12 × 6 – 10 + 4(3)
f(3) = 12 × 6 – 10 + (4 × 3)
f(3) = 12 × 6 – 10 + 12
f(3) = 72 – 10 + 12
f(3) = 62 + 12
f(3) = 74
