Question

what is the symbol of an inverse function​

Answer 1

Answer:

Notation. The inverse of the function f is denoted by f -1 (if your browser doesn't support superscripts, that is looks like f with an exponent of -1) and is pronounced "f inverse". Although the inverse of a function looks like you're raising the function to the -1 power, it isn't.

Answer 2

The symbol of an inverse function is $f^{-1}$.

• An inverse function f can be written as $\frac{1}{f}$ in the fraction form.
• To show the position of the function in the denominator, f is given a power of -1 in the inverse function.
• For example, if a function is given as f(x) = $\frac{3x}{2x-2}$ , then in the inverse function it would become, $f^{-1} (x)$ = $\frac{2x-2}{3x}$.
