Question

Q3. If p(x) = x - 1 then value of p(1) + P(-1) is ?​

Answer 1

Answer:

-2

Step-by-step explanation:

Given :

• p(x) = x - 1

To find :

• p(1) + p(-1)

Solution :

For p(1), x = 1 :

p(x) = x - 1

      = 1 - 1

      = 0

For p(-1), x = - 1

p(x) = x - 1

      = - 1 - 1

      = - 2

Now, p(1) + p(-1)

⇒ 0 + (-2)

⇒ - 2

Hence, the answer is -2.

Answer 2

Hello,

Here we go,

P(x) = x - 1

By replacing X by 1.

P(1) = 1- 1= 0

Now again replacing X by minus one.

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

Now by adding P(1) + p(-1)

0 + -2 = -2

I hope my answer will help you.
