Question

if p(x) = x+5 ,then find the value of p(x)+ p (-x)​

Answer 1

Answer:

p(x) + p(-x) = x+5+(-x)+(-5)

.= 0

Answer 2

Given:

p(x) = x+5

So, for finding p(-x), just substitute x as -x.

We get:

p(-x) = -x+5

We have to find the value of p(x)+p(-x).

This will be equal to:

p(x) + p(-x)

= x+5-x+5 = 10

$\huge\boxed{p(x)+p(-x)=10)$
