FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -In mathematics, an inverse is a function that serves to “undo” another function. That is, if f(x) produces y, then putting y into the inverse of f produces the output x. x . A function f that has an inverse is called invertible and the inverse is denoted by f−1.

Detailed explanation-2: -An inverse function essentially undoes the effects of the original function. If f(x) says to multiply by 2 and then add 1, then the inverse f(x) will say to subtract 1 and then divide by 2. If you want to think about this graphically, f(x) and its inverse function will be reflections across the line y = x.

Detailed explanation-3: -The inverse of an invertible matrix is denoted A-1. Also, when a matrix is invertible, so is its inverse, and its inverse’s inverse is itself, (A-1)-1 = A. Thus, there is at most one inverse.
