Answer 2

The value of p(x) + p(- x) is equal to 20.

Step-by-step explanation:

We have,

p(x) = 3x + 10

To find, the value of p(x) + p(- x) = ?

∴ p(x) = 3x + 10         ....... (1)

Put x = - 1 in equation (1), we get

p(- x) = 3( - x) + 10  

⇒ p(- x) = - 3x + 10  

∴ p(x) + p(- x)

= (3x + 10) + (- 3x + 10)

= 3x + 10 - 3x + 10

= 20

∴ The value of p(x) + p(- x) = 20

Thus, the value of p(x) + p(- x) is equal to 20.
