Question

6. If p(x) = x+8 then p(x) + p (-x) = ?
​

Answer 1

Answer :

p(x) + p(-x) = 16

Solution :

• Given : p(x) = x + 8
• To find : p(x) + p(-x) = ?

We have ;

p(x) = x + 8

Thus ,

p(-x) = -x + 8

Now ,

=> p(x) + p(-x) = (x + 8) + (-x + 8)

=> p(x) + p(-x) = x + 8 - x + 8

=> p(x) + p(-x) = 16

Hence ,

p(x) + p(-x) = 16
