Dany jest wielomian:
Oblicz W(0) ; W(-1) W(-2) i W(2)
W(x)=2x³-x²+2x-2
W(0)=2×0³-0²+2×3-2=-2
W(-1)=2×(-1)³-(-1)²+2×(-1)-2=-2-1-2-2=-7
W(2)=2×2³-2²+2×2-2=16-4+4-2=14
W(-2)=2×(-2)³-(-2)²+2×(-2)-2=-16-4-4-2=-26
W(x) = 2x^3 - x^2 + 2x - 2
W(0) = 2 * 0^3 - 0^2 + 2 * 0 - 2 = -2
W(-1) = 2 *(-1)^3 -(-1)^2 + 2*(-1) - 2 = -2-1-2-2 = -7
W(-2) = 2 *(-2)^3 -(-2)^2 + 2 *(-2) - 2 = -16-4-4-2 = -26
W(2) = 2 *2^3 - 2^2 + 2*2 - 2 = 16-4 + 4-2 =14
