minta tolong bantuin yang poin c sama d ajaa
Jawab:
komposisi
f(x)= 3 x+2
g(x) = 4x+ 1
h(x) = 2x + 3
c) fogog(x) =
= f { gog(x)}
= f { g (4x +1) }
= f { 4(4x+1) + 1}
= f { 16x + 5}
= 3(16x + 5 )
= 48x + 15
d) hogof(x) =
= h { gof (x)}
= h { g (3x+2)}
= h { 4(3x + 2) + 1 }
= h { 12 x + 9}
= 2(12x + 9) + 3
= 24x + 18 + 3
= 24x + 21
