17. Diketahui P(x) = 4x^2 – 2x + 1, hitung nilai P(0).
Jawab:
P(0) = 4(0)^2 – 2(0) + 1 = 0 – 0 + 1 = 1
18. Tentukan hasil dari P(x) = x^3 – 2x^2 + 4x – 3 jika x = 2.
Jawab:
P(2) = 2^3 – 2(2)^2 + 4(2) – 3 = 8 – 8 + 8 – 3 = 5
19. Jika P(x) = x^2 + 3x + 1, berapakah nilai P(3)?
Jawab:
P(3) = 3^2 + 3(3) + 1 = 9 + 9 + 1 = 19
