Question

find the value of the polynomial at the indicated values of variables p(x)=3x^3+2x-3x^2+4;x=2,-2​

Answer 1

Answer:

p(2) =20, p(-2) =-36

Step-by-step explanation:

when x=2

p(2)=3(2^3)+2(2)-3(2^2)+4

p(2)=3(8)+4-3(4)+4

p(2)=24+4-12+4

p(2)=20

when x=-2

p(-2) =3(-2^3)+2(-2)-3(-2^2)+4

p(-2)=3(-8)-4-3(4)+4

p(-2)=-24-4-12+4

p(-2)= -36
