Question

If P(x) = x^ 3 – 1, then the value of P(1) + P(-1) is

Answer 1

Answer:

P(1)+P(-1)=-2

Step-by-step explanation:

Given,

P(x)=x³-1

therefore,

P(1)=1³-1=0

And,

P(-1)=(-1)³-1=-2

therefore,

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

=0-2

=-2

That's your answer. I hope it will help you.

Answer 2

Answer:

P(1)+P(-1)=-2

Step-by-step explanation:

Given,

P(x)=x³-1

therefore,

P(1)=1³-1=0

And,

P(-1)=(-1)³-1=-2

therefore,

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

=0-2

=-2
