Question

what is the symbol of an inverse function?​

Answer 1

Answer:

The inverse of the function f is denoted by f -1

Step-by-step explanation:

An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing. We can write this in terms of the composition of f and g as g(f(x))=x.

Answer 2

The inverse of the function f is denoted by$f^{-1}$ and is pronounced "f inverse".

Explanation:

• An inverse function is a function that undergoes the action of another function.
• An inverse function is a function that returns the original value for which a function has given the output.
• If f(x) is a function which that gives output y, then the inverse function of y i.e.$f^{-1} (y)$ will return the value x.
• An inverse function reverses the inputs and outputs.
• Some functions have no inverse function, as a function cannot have multiple outputs.
