The graph of a function 1.1. Graphs. Definition 1.1. A real function is a function f : D → R with D R (D is usually an interval or a union of intervals.) Thus, real functions are functions whose 'inputs' and 'outputs' are real num- bers, and these are the functions which are...
In graph a). To each value of x there is one and only one value of y. Any straight line parallel to the y-axis will cut that graph only once. The coördinate pairs of a functionConsider the function y = x2. The variable y now signifies the y-coördinate, and x, the x-...

Graphs of Functions If f is a function with domain D , its graph consists of the points in the Cartesian plane(笛卡尔平面) whose coordinates are the input-output pairs for f . In set notation , the graph is {(x,f(x))|x∈D} EXAMPLE Graph the function y=x2 over the interval [-...

A function is a correspondence between two sets X and Y that assigns to each element x of set X exactly one element y of set Y. For each element x in X, the corresponding element y in Y is called thevalueof the function at x. The set X is called thedomainof the function, and ...
Recall that we call this behavior the end behavior of a function. As we pointed out when discussing quadratic equations, when the leading term of a polynomial function, anxnanxn, is an even power function, as x increases or decreases without bound, f(x)f(x) increases without bound. When...
