Question

Which function is the inverse of Fx) = bx?

Answer 1

Answer:

${f}^{ - 1} (x) = \frac{b}{x}$

Step-by-step 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:

$y= \frac{b}{x}$

Therefore the inverse function is

${f}^{ - 1} (x) = \frac{b}{x}$
