apabila f(x)=x-1/5 dan g^-1(x)=3-x/2 maka (fog) ^-1(6)

F⁻¹ (x) = (x - 1) / 5
y = (x - 1) / 5
tukar x dengan y
x = (y - 1) / 5
y - 1 = 5x
y = 5x + 1
f (x) = 5x + 1

g⁻¹ (x) = (3 - x) / 2
y = (3 - x) / 2
tukarkan x dengan y
x = (3 - y) / 2
3 - y = 2x
-y = 2x - 3
y = -2x + 3
y = 3 - 2x
g (x) = 3 - 2x

(f o g) (x) = 5(3 - 2x) + 1
= 15 - 10x + 1
(f o g) (x) = 16 - 10x
y = 16 - 10x
tukarkan x dan y

x = 16 - 10y
10y = 16 - x
y = (16 - x) / 10
(f o g)⁻¹ = (16 - x) / 10
