Question

Oblicz wartość wielominu dla:

a) x=-2,

b) x=

c) x=0

d) x=1

Answer 1

H(x)=3x⁴-5x³+2x²-1

 

a) x=-2

H(-2)=3*(-2)⁴-5*(-2)³+2*(-2)²-1

H(-2)=3*16+5*8+2*4-1

H(-2)=48+40+8-1

H(-2)=95

 

b) x=-3/2

H(-3/2)=3*(-3/2)⁴-5*(-3/2)³+2*(-3/2)²-1

H(-3/2)=3*81/16 + 5*27/8 + 2*9/4 -1

H(-3/2)=243/16 + 270/16 + 72/16 -16/16

H(-3/2)=569/16

 

c) x=0

H(0)=-1

 

d) x=1

H(1)=3*1-5*1+2*1-1

H(1)=3-5+2-1

H(1)=-1
