Answer 1

Jawaban:

jawabannya e. 1

Penjelasan dengan langkah-langkah:

f(x) = 2x-5

g(x) = 3x+4

karena h^-1 = (g°f)^-1 (x) = (f^-1 ° g^-1 ) (x)

(g°f)^-1 (x) = g(f(x)) = 3(2x-5) +4

= 6x-15+4

= 6x-11

y= 6x-11

6x= y +11

x = (y +11) /6

(f^-1 ° g^-1 ) (x) = (x+11) /6

sehingga

(f^-1 ° g^-1 ) (-5)

= (-5+11) /6

= 6 / 6

= 1
