_________________✧✧✧✧___________________
Soal 1
f(x) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(1) = 2(1.1.1) + 2(1.1) - 2(1) × 2(1) - 5 × 2(1.1)
f(1) = 2(1) + 2(1) - 2(1) × 2(1) - 5 × 2(1)
f(1) = 2 + 2 - 2 × 2 - 5 × 2
f(1) = 2 + 2 - 4 - 5 × 2
f(1) = 2 + 2 - 4 - 10
f(1) = 4 - 4 - 10
f(1) = 0 - 10
f(1) = -10
Soal 2
f(x) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(2) = 2(2.2.2) + 2(2.2) - 2(2) × 2(2) - 5 × 2(2.2)
f(2) = 2(8) + 2(4) - 2(2) × 2(2) - 5 × 2(4)
f(2) = 16 + 8 - 4 × 4 - 5 × 8
f(2) = 16 + 8 - 16 - 5 × 8
f(2) = 16 + 8 - 16 - 40
f(2) = 24 - 16 - 40
f(2) = 8 - 40
f(2) = -32
Soal 3
f(x) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(3) = 2(3.3.3) + 2(3.3) - 2(3) × 2(3) - 5 × 2(3.3)
f(3) = 2(27) + 2(9) - 2(3) × 2(3) - 5 × 2(9)
f(3) = 54 + 18 - 6 × 6 - 5 × 18
f(3) = 54 + 18 - 36 - 90
f(3) = 72 - 36 - 90
f(3) = 36 - 90
f(3) = -54
Soal 4
f(x) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(4) = 2(4.4.4) + 2(4.4) - 2(4) × 2(4) - 5 × 2(4.4)
f(4) = 2(64) + 2(16) - 2(4) × 2(4) - 5 × 2(16)
f(4) = 128 + 32 - 8 × 8 - 5 × 32
f(4) = 128 + 32 - 64 - 160
f(4) = 160 - 64 - 160
f(4) = 96 - 160
f(4) = -64
Soal 5
f(x) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(5) = 2(5.5.5) + 2(5.5) - 2(5) × 2(5) - 5 × 2(5.5)
f(5) = 2(125) + 2(25) - 2(5) × 2(5) - 5 × 2(25)
f(5) = 250 + 50 - 10 × 10 - 5 × 50
f(5) = 250 + 50 - 100 - 250
f(5) = 300 - 100 - 250
f(5) = 200 - 250
f(5) = -50
Soal 6
f(6) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(6) = 2(6.6.6) + 2(6.6) - 2(6) × 2(6) - 5 × 2(6.6)
f(6) = 2(216) + 2(36) - 2(6) - 5 × 2(36)
f(6) = 432 + 72 - 12 - 360
f(6) = 504 - 12 - 360
f(6) = 492 - 360
f(6) = 132
Soal 7
f(7) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(7) = 2(7.7.7) + 2(7.7) - 2(7) × 2(7) - 5 × 2(7.7)
f(7) = 2(343) + 2(49) - 2(7) × 2(7) - 5 × 2(49)
f(7) = 686 + 98 - 14 × 14 - 5 × 98
f(7) = 686 + 98 - 192 - 490
f(7) = 784 - 192 - 490
f(7) = 592 - 490
f(7) = 102
Soal 8
f(8) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(8) = 2(8.8.8) + 2(8.8) - 2(8) × 2(8) - 5 × 2(8.8)
f(8) = 2(512) + 2(64) - 2(8) × 2(8) - 5 × 2(64)
f(8) = 1.024 + 128 - 16 × 16 - 5 × 128
f(8) = 1.024 + 128 - 256 - 640
f(8) = 1.152 - 256 - 640
f(8) = 896 - 640
f(8) = 256
Soal 9
f(9) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(9) = 2(9.9.9) + 2(9.9) - 2(9) × 2(9) - 5 × 2(9.9)
f(9) = 2(729) + 2(81) - 2(9) × 2(9) - 5 × 2(81)
f(9) = 1.458 + 162 - 18 × 18 - 5 × 162
f(9) = 1.458 + 162 - 324 - 810
f(9) = 1.620 - 324 - 810
f(9) = 1.296 - 810
f(9) = 486
Soal 10 (Bonus)
f(10) = 2x³ + 2x² - 2x × 2x - 5 × 2x²
f(10) = 2(10.10.10) + 2(10.10) - 2(10) × 2(10) - 5 × 2(10.10)
f(10) = 2(1.000) + 2(100) - 2(10) × 2(10) - 5 × 2(100)
f(10) = 2.000 + 200 - 20 × 20 - 5 × 200
f(10) = 2.000 + 200 - 400 - 1.000
f(10) = 2.200 - 400 - 1.000
f(10) = 1.800 - 1.000
f(10) = 800
