Tentukan f(x) jika fungsi f:R => R, g:R =>R didefenisi oleh g(x) dan (g°f) (x).

d) g(x) =
3x+2
-------
4x-1

dan (g°f) (x)
= 5x-2
---------
4x+1

$(gof)(x)=g(f(x)) \\ \frac{5x-2}{4x+1}= \frac{3(f(x))+2}{4(f(x))-1} \\ 20x(f(x))-5x-8(f(x))+2=12x(f(x))+8x+3(f(x))+2 \\ 8x(f(x))-11(f(x))=13x \\ (f(x))(8x - 11)=13x \\ f(x)= \frac{13x}{8x-11}$

3 + ½ hasilnya berapa? bajak adiknya

MATRIKS 100 Pointyang diatas no 1) itu 4 pangkat x+2yyang no 2) 2a+b

100 PointJika f invers (k) =4 Maka Nilai k ??ps : Soal ada di gambar

F(2x+3) =x+3------2x-4 maka f(x) -1 ???
