Q.
f(x) = 5x × x³ + 8² – 12
f(3) = (5 x 3) × (3³) + (8 x 8) – 12
f(3) = 15 × 27 + 64 – 12
f(3) = 405 + 64 – 12
f(3) = 469 – 12
f(3) = 457
Jawaban:
f(x) = 5x × x³ + 8² – 12
- f(5) = (5×3) × (3×3×3) + (8×8) – 12
- f(5) = 15 × (9×3) + 64 – 12
- f(5) = 15 × 27 + 64 – 12
- f(5) = 405 + 64 – 12
- f(5) = 469 – 12
- f(5) = 457
nilai f(5) adalah 457
