Question

f p(x) = 5x+7 then p(x) + p(-x) =


a) 14 b) 10x c) 10x+14 d) 0​

Answer 1

p(x) = 5x + 7 .........................(a)

Replace x by -x,

p(-x) = 5(-x) + 7 = -5x + 7 .........(b)

Add (a) and (b),

p(x) + p(-x) = 5x + 7 + [-5x + 7]

= 5x + 7 - 5x + 7

= 7 + 7

= 14

Hence, p(x) + p(-x) = 14

Thus, correct answer is -» (a) 14
