Answer: ( f + g ) ( 2 ). Solution. Step 1. Find ( f + g ) ( x ). Since ( f + g ) ( x ) = f ( x ) + g ( x ) then;. ( f + g ) ( x ) = ( 2x + 1 ) + (x. 2. + 2x – 1 ). = 2x + 1 + x. 2. + 2x – 1. = x. 2. + 4x. Step 2. Find ( f + g ) ( 2 ). To find the solution for ( f + g ) ( 2 ) ... ( f – g ) ( 2 ) = 3 (2) – 6.
