Intuitively, a function is a process that associates each element of a set X, to a single element of a set Y Formally, a function f from a set X to a set Y is defined by a set G of ordered pairs (x, y) with x ∈ X, y ∈ Y, such that every element of X is the first component of exactly one ordered pair in G In other words, for every x in X, there is exactly one element y such that theConcave down if a < 0 The domain of the function is all real numbersFor each x x value, there is one y y value Select few x x values from the domain It would be more useful to select the values so that they are around the x x value of the absolute value vertex Tap for more steps Substitute the x x value − 2 2 into f ( x) = x f ( x) = x
