Question

If p(x) = 2x3 - 4x2 +4x – 5 then find p(-2) and p(1).

Answer 1

Step-by-step explanation:

p(-2)=(2*-2*3)-(4*-2*2)+(4*-2)-5

       =-12+16-8-5

       =-17+8

       =-9

p(1)=(2*1*3)-(4*1*2)+(4*1)-5

    =6-8+4-5

    =10-13

    =-3

Answer 2

Answer:p (-2)=-45, p(1)=-3

Step-by-step explanation:p (x)=-2,1

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

=2 (-8)-4 (4)-8-5

=-16-16-13

=-32-13

=-45

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

=2 (1)-4 (1)+4-5

=2-4+4-5

=6-9=-3
