Answer 1

Answer:

$p(x) = {x}^{3} - 1 \\ we \: are \: asked \: to \: find \: \\ p(1) + p( - 1) \\ = (1 - 1) + ( - 1 - 1) \\ = - 2$

Answer 2

Answer:

p(x) = x³ - 1

__________________________

now,

p(1) = (1)³ - 1 = 1 - 1 = 0

__________________________

&

p(-1) = (-1)³ - 1 = -1 -1 = (-2)

___________________________

p(1) + p(-1) = 0-2= (-2)
