If p (x) = x + 3, then what is the value of p (x) + p ( - x) ?

p (x) + p (-x) = 6 is

Step-by-step explanation:

In this question, we are tasked with calculating what p (x) + p (-x) will be

From the question, we know that p (x) = x + 3

Then p (-x) will be p (-x) = - x + 3

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

p (x) + p (-x) = 3 + 3 = 6
