Fungsi f rr dan g rr ditentukan oleh f(x x 2 dan g(x 2x maka fog 1))

Fog(x) = f(2x) = 2x+ 2fog^-1(2x+2) = x2x+2 = a(x+1) = 1/2 ax = 1/2 a - 1(fog)^-1(a) = 1/2 a - 1(fog)^-1(x) = 1/2 x - 1= (x-2)/2.gof (x) = g(x+2) = 2(x+2) = 2x+ 4(gof)^-1 (2x+4) = x2x + 4= a2x = a-4x = (a-4)2(gof)^-1(a) = (a-4)/2

(gof)^-1(x) = (x-4)/2

  loh ga cari f invers sama g invers dulu?
