Expert Answer
Answer :  (i)  Given : f(x)= -2x + 5
To find  : The value of 2f(x)+f(-x)
 
Now ,
 f(x)= -2x + 5..................(1)

Replacing x by -x , we get ,
 f(-x)= 2x + 5 .................(2)
 
Now as asked by the question 
= 2 f(x) - f(-x) 
= 2 ( -2x + 5) - (2x+5)        {using (1) and (2) }
= -4x + 10 - 2x -5
= - 6x  + 5 Answer
