Question

6. If p(x) = x + 5, then find p(x) + p (-x) is​

Answer 1

Answer:

GIVEN THAT,

p(x) = x+3

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

Now,

p(-x) + p(x)

= -x + 3 + x + 3

= 3 + 3

= 6

The value of p(-x)+p(x) is 6.

Step-by-step explanation:

The given function is

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

Substitute x=-x, it the given function.

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

Now add the equations (1) and (2).

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

Combined like terms.

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

p(-x)+p(x)=6

Therefore the value of p(-x)+p(x) is 6.
