Question

If p(x) = x - 3, then p(x) + p(–x) is equal to

Answer 1

p(x) = x - 3 .................(1)

This is an equation which is true for all real values of x.

Put x = -x

=> p(-x) = (-x) - 3 = -x - 3 ............(2)

Add (1) and (2),

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

= -3 - 3

= -6

Thus, the correct answer is -6.

Answer 2

Answer:

• p(x) = x - 3

x = 3

• p(-x) = x - 3

x = 3

-x = -3

• p(x) + p(-x)

3 + ( -3 )

3 - 3
