( f + g ) ( x ) = f ( x ) + g ( x ) ( f + g ) ( x ) = − 6 x − 1 + 4 x 2 = 4 x 2 − 6 x − 1
f ( x ) = − 6 x − 1 g ( x ) = 4 x 2 S o : ( f + g ) ( x ) = 4 x 2 − 6 x − 1
Please mark as best! =)
The solution for ( f + g ) ( x ) is 4 x 2 − 6 x − 1 . This is found by adding the two given functions f ( x ) and g ( x ) .
