Question

If p(x)=x+3x-2x + 4, then find the value of
p(2) + p(-2) - P(O).
​

Answer 1

if x = 2

p(2) = x+3x-2x+4

       = 2x + 4

       = 2(2) + 4

       = 4+4

       = 8

p(-2) = 2x+4

        = 2(-2) + 4

        = -4 + 4

        = 0

p(0) = 2x + 4

      = 0 +4

      = 4

p(2) + p(-2) - p(0)

= 8 + 0 -4

=4
