Question

F(x) = 1 - 1/2 x dan g(x) = 2x - 4 , jika peta (gof)-1 (x) = 1 adalah ?

Answer 1

F-1(x)= 2-2x
g-1(x) = (x+4)/2

(gof)-1 = (f-1 o g-1)
jadi, 2-2(1+4)/2 *dua di coret*
      = 2-5 
      = -3

coba dicek dulu ya hehehehhehe

Answer 2

f-1(x)= 2-2x
g-1(x) = (x+4)/2

(gof)-1 = (f-1 o g-1)
 2-2(1+4)
      = 2-5 
      = -3
