Question

Which function is the inverse of Fx) = bx?

Answer 1

F-1(y) = logby

Explanation:

Answer 2

`{f}^( - 1) (x) = (b)/(x)`

Explanation:

The given function is

`f(x) = bx`

To find the inverse function, we let

`y = bx`

We interchange x and y to get:

`x = by`

We now solve for y to get:

`y= (b)/(x)`

Therefore the inverse function is

`{f}^( - 1) (x) = (b)/(x)`
