Penjelasan dengan langkah-langkah:
misal kan invers f(x) = f¹(x) = f^-¹(x)
diperoleh :
a = 2
b = -1
c = 3
d = 4
maka sesuai rumus invers, :
f¹(1) = -5/1 = -5
x (3.f¹(x) + 4) = 2.f¹(x) -1
3x.f¹(x) + 4x = 2.f¹(x) -1
3x.f¹(x) -2.f¹(x) = -4x -1
f¹(x) (3x -2) = -(4x + 1)

Cara 1
misal kan invers f(x) = f¹(x) = f^-¹(x)
diperoleh :
a = 2
b = -1
c = 3
d = 4
maka sesuai rumus invers, :
f¹(1) = -5/1 = -5
Cara 2
misal kan invers f(x) = f¹(x) = f^-¹(x)
x (3.f¹(x) + 4) = 2.f¹(x) -1
3x.f¹(x) + 4x = 2.f¹(x) -1
3x.f¹(x) -2.f¹(x) = -4x -1
f¹(x) (3x -2) = -(4x + 1)
f¹(1) = -5/1 = -5
