W(x)=4x³ - 2x² + 3x + 1/2 , P(-1, 8 1/2)

w(-1)=8 i 1/2
4(-1)³-2(-1)²+3(-1)+1/2=-4-2-3+1/2=-8 i 1/2 nie nalezy



w(x)=4x³ - 2x² + 3x + 1/2 , Q(1/2, 2)
W(1/2)=4(1/2)³-2(1/2)²+3(1/2)+1/2=1/2-1/2+3/2+1/2=4/2=2 nalezy



w(x)=4x³ - 2x² + 3x + 1/2 , R(-1/2, -1)
w(-1/2)=4(-1/2)³-2(-1/2)²+3(-1/2)+1/2=-1/2-1/2-3/2=-5/2 nie nalezy
