Question

If p(x) = x + 3x - 2x + 4, then find the value of
p(2) +p(-2) - p(0)
[CBSE 2012​

Answer 1

P(2)= 8 // P(-2)= 0 // P(0)= 4

Sum of all is 8+0+4= 12

Answer 2

Answer:

12

Step-by-step explanation:

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

==> p(x) = 2x + 4

Now,

p(2) = 2(2) + 4 = 4 + 4 = 8

p(-2) = 2(-2) + 4 = -4 + 4 = 0

p(0) = 2(0) + 4 = 4

Finally, p(2) + p(-2) - p(0) = 8 + 0 + 4 = 12

I hope this answer is helpful :)
