tolong dijawab yah. Yg bener ya!! Lumayan poinnya besar lho!
1. F(x)= x+3/x-1
x tdk sm dgn 1
g(x) =x+5
(g o f) (3)=....
2. f(x)= 2x kuadrat+3x-5
g(x)= 3x-2
(g o f)(a)=-11
nilai a??
Makasihhhhh!!!!!

1. f(x) = x+ 3/x-1
g(x) = x+5
gof(x) = g(f(x))
= x+5
=(x+3/x-1)+5
=(x²-x+3/x-1)+5
=(x+3/x-1)+5
=x+3+5x-5/x-1
=6x-2/x-1
gof(3) = 6(3)-2/3-1
= 18-2/2
= 16/2
=8
semoga membantu :)
