**Precalculus 4.1 - One-to-One and Inverse Functions**

(3) For a one-to-one function, the graph of the inverse function is obtained by reﬂecting the graph of the function about the y = x line. In particular, a function equals its own inverse iﬀ its graph is... is a function if and only if f is one-to-one. For a function y = f ( x ), the inverse relation of f is a function if and only if the graph of f passes the

Precalculus 4.1 OnetoOne and Inverse Functions 4 January 06, 2017 If a function is one‐to‐one, then it has an inverse. Interchanging the first and second coordinates of each ordered pair in a relation produces the inverse function. If a relation is defined by an equation, interchanging the variables produces an equation of the inverse relation. Precalculus 4.1 OnetoOne... One-to-One Functions. Inverse Functions. Equations of Inverses. 4.1 - 2. Inverse Operations. Addition and subtraction are . inverse operations: starting with a number . x, adding 5, and subtracting 5 gives . x . back as the result. Similarly, some functions are . inverses . of each other. For example, the functions. defined by. 1 ( ) 8 and ( ) 8. f gxx x x == are inverses of each other with

Inverse Function The inverse of a one-to-one functionf is the function f 1, which is obtained from f by interchanging the coordinates in each ordered pair of f. EXAMPLE 1 Identifying invertible functions Determine whether each function is invertible. If it is invertible, then ﬁnd the inverse function. a) f (2, 4), ( 2, 4), (3, 9) b) g 2, 1 2, 5, 1 5, 7, 1 7 c) h (3, 5), (7, 9) Solution a... In mathematics, an injective function or injection or one-to-one function is a function that preserves distinctness: it never maps distinct elements of its domain to the same element of its codomain. In other words, every element of the function's codomain is the image of at most one element of its domain.
