Which pair of expressions represents inverse functions?
faust18 [17]

In this question , we have to find, which option represents inverse functions.

Let's check out option b

Let it be y

So we have

y = \frac{x+3}{4x-2}

Switching x and y and solving for y,

x = \frac{y+3}{4y-2}

Performing cross multiplication

4xy -2x = y+3

Combining like terms

y(4x-1) = 3+2x

y = \frac{2x+3}{4x-1}
\\
f^{-1} (x) = \frac{2x+3}{4x-1}

Which is same as of the other function.

So correct option is b .
