tolong saya dulu kaka kaka malam ini kalau saya tidak kumpul hari senin kena hukuman dari guru sudah
f(x) = 2x + 4
g(x) = 3x
h(x) = x² + 1
a. ( f o g ) = f [ g(x) ]
= f [ 3x ]
= 2( 3x ) + 4
= 6x + 4
( ( f o g ) o h ) (x) = ( f o g ) [ h(x) ]
= ( f o g ) [ x² + 1 ]
= 6( x² + 1 ) + 4
= 6x² + 6 + 4
= 6x² + 10
b. ( g o h ) (x) = g [ h(x) ]
= g [ x² + 1 ]
= 3( x² + 1 )
= 3x² + 3
( f o ( g o h ) ) (x) = f [ ( g o h )(x) ]
= f [ 3x² + 3 ]
= 2( 3x² + 3 ) + 4
= 6x² + 6 + 4
= 6x² + 10
