Question

If p(x)=x+3, then p(x)+p(−x) is equal to :​

Answer 1

Given:-

• p(x)=x+3.

To Find:-

• Value of p(x)+p(−x).

Solution:-

Putting x=-x in the equation p(x)=x+3.

$p( - x) = - x + 3$

Now, Adding p(x)+p(−x)

$p(x)+p(−x) = x + 3 - x + 3$

$= > + 6$

Answer 2

Given that:

p (x) = x + 3

= p(-x) = -x + 3

Now,

p(-x) + p (x)

-x + 3 + x + 3

= 3+3

= 6
