ditanya f(4)
berarti 2x - 1 = 4
2x = 5
x = 5/2
f(4) = 5/2 / (5/2 - 2)
f(4) = 5/2 / (1/2)
f(4) = 5 (C)
8. f(x) = 3x + 1
{f(x)^2} = (3x + 1)^2 = 9x^2 + 6x + 1
f(x^2) = 3(x^2) + 1 = 3x^2 + 1
2 f(x) = 2(3x + 1) = 6x + 2
Jadi : 9x^2 + 6x + 1 - (3x^2 + 1) - (6x + 2)
: 9x^2 + 6x + 1 - 3x^2 - 1 - 6x - 2
: 6x^2 - 2 ( E )
14. f(x) = 2x + 1
g(x) = 3x + 1 / 4x - 1
karena (g o f)(x) maka
3 ( 2x + 1 ) + 1 / 4(2x + 1) - 1
6x + 3 + 1 / 8x + 4 - 1
6x + 4 / 8x + 3 ( C )
baru kayaknya sih kak..
aku belom belajar sampe sana..
