Me ayudan por favor

Answer 1

Respuesta:

P(1)=-5

P(-1)=-13

P(2)=-1

P(-3)=-93

P(4)=67

P(1/2)=-19/4

Explicación paso a paso:

P(1) = 2(1)^3 - 4(1)^2 + 2.1 - 5   = 2-4+2-5       =P(1) = -5

P(-1) = 2(-1)^3  - 4(-1)^2 + 2(-1) -5 = -2-4-2-5  =P(-1) = -13

P(2)=2(2)^3 -4(2)^2 + 2(2) -5 = 2.8 - 4.4 + 4-5= 16-16-1=  P(2)=-1

P(-3) =2(-3)^3-4(-3)^2+2(-3)-5=2(-27)-4(9)-6-5=-54-28-11= -82-11 P(-3)=-93

P(4)=2(4)^3 -4(4)^2+2(4)-5= 2.64 -4.16 +8-5=128-64+3=P(4)=67

P(1/2)=2(1/2)^3-4(1/2)^2+2(1/2)-5= 2(1/8)-4(1/4)+1-5=1/4-1+1-5=1/4-5=  P(1/2)=-19/4

Espero te sirva
