2f(x)+ f(-x)=1+x multiplied by 2
4f(x)+ 2f(-x)=2+2x (1)
Put x = -x
f(x)+ 2f(-x)=1-x (2)
Subtract 2 from 1
f(x)=1+3x/3
And I am guessing you know how to find (f) prime
So, f'(x) comes out to be 1
4f(x)+ 2f(-x)=2+2x (1)
Put x = -x
f(x)+ 2f(-x)=1-x (2)
Subtract 2 from 1
f(x)=1+3x/3
And I am guessing you know how to find (f) prime
So, f'(x) comes out to be 1
