Intro to inverse functions (article) | Khan Academy
WEBLearn what the inverse of a function is, and how to evaluate inverses of functions that are given in tables or graphs. Inverse functions, in the most general sense, are functions that "reverse" each other. For example, here we see that function f takes 1 to x , 2 to z , and 3 to y . A mapping diagram.

WEBIn mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by. For a function , its inverse admits an explicit description: it sends each element to the unique element such that f(x) = y .

WEBNo, all strictly growing or strictly decreasing functions have an inverse. If it is not strictly growing/decreasing, there will be values of f (x) where. f (x) = f (y), x not equal to y. So, its inverse g would have two values for f (x), as g ( f (x) …

WEB4 days ago · Inverse Functions. An inverse function is the "reversal" of another function; specifically, the inverse will swap input and output with the original function. Given a function \ ( f (x) \), the inverse is written \ ( f^ {-1} (x) \), but this should not be read as a negative exponent.

WEBLearn how we can tell whether a function is invertible or not. Inverse functions, in the most general sense, are functions that "reverse" each other. For example, if f takes a to b , then the inverse, f − 1 , must take b to a .
