Question

Jawab ya besok kumpulin nih

Answer 1

Jawaban:

(x-1)/(3x-9)

Penjelasan dengan langkah-langkah:

= f(g(x))

= 2(1/(3x-1))+3

= 2/(3x-1)+3

= (9x-1)/(3x-1)

Inversnya:

y= (9x-1)/(3x-1)

3xy-y= 9x-1

3xy-9x= y-1

x(3y-9)= y-1

x= (y-1)/(3y-9)

f‐¹(x)= (x-1)/(3x-9)

Answer 2

Jawaban:

( fog x ) = f(g(x)

=2g(x) + 3

= 2(1/3x-1) +3

= 2/3x-2+3

= 2/3x+1

misal (fog) (x) = y

maka y = 2/3x+1

2/3x= y - 1

x = (3y-3)/2

=> Jadi ( fog ) ^-1(x) = (3x-3) / 2
