Question

Find the inverse of each function. h ( n ) = 4/n − 2

Answer 1

$4(x + 2) = {h(n)}^{- 1}$

Answer 2

Answer: 4/(n+2)

h(n)=4/n-2

Let y=h(n),then,

→y=4/n-2

→4/n=y+2

→n=4/(y+2)

Interchanging the role of y and n here to find inverse,

y=4/(n+2)  →inverse function

i.e. , inverse of h(n)=4/(n+2)
