F(x)= 3x2 – 2x - 8,, x պատկանում է [-2;2]
F(-2)= 3*(-2)2-2*(-2) – 8 = -12+4-8 = -16
F(-1,5)= 3*(-1,5)2 -2(-1,5) -8 = -6,75 + 3 – 8 = -11,75
F(-1)= 3*(-1)2 – 2*(-1) -8 = -6+ 2 -8 = -12
F(-0,5)= 3*(-0,5)2 – 2*(-0,5) – 8 = - 0,75 + 1 - 8 = -7,75
F(0)= 0 - 0 -8 = -8
F(0,5)= 3*(0,5)2 -2*(0,5) – 8 = 0,75 – 1 – 8 = -8,25
F(1)= 3*1-2*1-8 = 3-2-8= -7
F(1,5)= 3*1,52 – 2*1,5 – 8 = 6,75 – 3 – 8 = -4,25
F(2)= 3*4-2*2-8 = 12-4-8 = 0
