Ordered pairs and function

WebDefine a function from a set of ordered pairs; Identify domain and range. Relations can be written as ordered pairs of numbers or as numbers in a table of values. By examining the inputs (x-coordinates) and outputs (y-coordinates), you can determine whether or not the relation is a function. Remember, in a function each input has only one output. WebSep 27, 2024 · We have found inverses of function defined by ordered pairs and from a graph. We will now look at how to find an inverse using an algebraic equation. The method uses the idea that if \(f(x)\) is a one-to-one function with ordered pairs \((x,y)\), then its inverse function \(f^{−1}(x)\) is the set of ordered pairs \((y,x)\).
