f(x) = 23x + 42x²

f(3) = 23(3) + 42(3²)

f(3) = (23 × 3) + 42(3²)

f(3) = (23 + 23 + 23) + 42(3²)

f(3) = (46 + 23) + 42(3²)

f(3) = 69 + 42(3²)

f(3) = 69 + 42(3 × 3)

f(3) = 69 + 42(9)

f(3) = 69 + (42 × 9)

f(3) = 69 + (42 + 42 + 42 + 42 + 42 + 42 + 42 + 42 + 42)

f(3) = 69 + (84 + 42 + 42 + 42 + 42 + 42 + 42 + 42)

f(3) = 69 + (126 + 42 + 42 + 42 + 42 + 42 + 42)

f(3) = 69 + (168 + 42 + 42 + 42 + 42 + 42)

f(3) = 69 + (210 + 42 + 42 + 42 + 42)

f(3) = 69 + (252 + 42 + 42 + 42)

f(3) = 69 + (294 + 42 + 42)

f(3) = 69 + (336 + 42)

f(3) = 69 + 378

f(3) = 447

Penyelesaian ☁️

• f(x) = 23x + 42x²

• f(3) = 23(3) + 42(3²)

• f(3) = (23 + 23 + 23) + 42(3²)

• f(3) = (46 + 23) + 42(3²)

• f(3) = 69 + 42(3 × 3)

• f(3) = 69 + 42(9)

• f(3) = 69 + (42 × 9)

• f(3) = 69 + (42 + 42 + 42 + 42 + 42 + 42 + 42 + 42 + 42)

• f(3) = 69 + (84 + 42 + 42 + 42 + 42 + 42 + 42 + 42)

• f(3) = 69 + (126 + 42 + 42 + 42 + 42 + 42 + 42)

• f(3) = 69 + (168 + 42 + 42 + 42 + 42 + 42)

• f(3) = 69 + (210 + 42 + 42 + 42 + 42)

• f(3) = 69 + (252 + 42 + 42 + 42)

• f(3) = 69 + (294 + 42 + 42)

• f(3) = 69 + (336 + 42)

• f(3) = 69 + 378
