1. If f(x) = 3x - x3 and g(x) = x3, compute: (f + g) (x), (f - g)(x), (fg)(x), (fig)(x). f(8(1)), and g( f (1)). f ( x ) = 3 x - x 3 g (x) = x3(f /g) (x)=3x-x3 ( f+ g ) ( x ) = 3 x - x3 + x 3 lethal ! x 3 ( fig) ( x ) = 3x and lembe to do men( f 1 9 ) (x ) = 3- X2 ( f - g ) ( x ) = 3x- x5 - x ( f- g) ( x ) = 3 x- 2 x3 f ( g(1 ) ) = ( fg) (x ) = (3 x-x3) (x3) ( fg ) ( x ) = 3 x4 - xb 2.
