Question

If p ( x ) = x cube - x square + x + 1 . find the value of p(-1) + p ( 1 ) / 2​

Answer 1

Answer:

-0.125 or -⅛

Step-by-step explanation:

p(x)=x³-x²+x+1

p(-1)=(-1)³-(-1)²+(-1)+1

p(-1)=-1-1-1+1

p(-1)=-2

p(x)=x³-x²+x+1

p(½)=(½)³-(½)²+½+1

p(½)=⅛-¼+½+1

p(½)=1.875

p(-1)+p(½)

-2+1.875

-0.125
