Make me as a Brainlist pls

Step-by-step explanation:

f(x) =  {x}^{3}  + x \\  =  > f(1) =  {1}^{3}  + 1 \\  =  > 1 + 1 = 2 \\  =  > 2

f(x) =  {x}^{3}  + x \\  =  > f( - 1) =  { (- 1)}^{3}   + ( -  1) \\  =  >  - 1  -  1 =  - 2 \\  =  > -  2

According to the question :-

f(1) + f( -1 ) \\  =  > 2 + ( - 2) \\  =  > 2 - 2 = 0 \\  =  > 0
