Step-by-step explanation:

Given :-

p(x) = x+4.

Find :-

The value of p(x) + p( - x)

Solution :-

Let p(x) = 0 then

$= > x + 4 = 0 \\ = > x = - 4$

$if \: x = - 4 \\ = > - x = - ( - 4) \\ = > - x = + 4$

$p(x)= x+4 \\ = > p( - 4) = - 4 + 4 = 0 \\ \\ = > p( - x) = x+4 \\ = > p( - x) = + 4 + 4 = 8$

$p(x) + p( - x) \\ = > 0 + 8 \\ = > 8$

Conclusion :-)

Thus , the value of p(x) + p( - x) is 8. So, option a) 8 is the correct answer
