1.1 Functions and Their Graphs Functions;Domain and Range y=f(x) In this notation, the symbol f represents the function, the letter x is the independent variable(自变量) representing the input value of f, and y is the dependent variable(因变量) or output value of f at x. The set D ...
This chapter focuses on graphs and functions. There is a natural correspondence between the real numbers and the points on a straight line, and there is also a natural correspondence between ordered pairs of real numbers and the points of a plane. The Cartesian coordinate system establishes this...

Identifying Functions Decide whether the relation shown in the input-output diagram is a function. If it is a function, give the domain and the range. The relation IS a function. For each input there is exactly one output. The domain of the function is the set of input values 1, 2, 3...
When you need to do co-function graphs, you may be tempted to try to compute a lot of plot points. But all you really need to know are your sine, cosine, and tangent functions. Take what you know, and flip that around for whichever co-function you're wanting to graph. From that,...

A function is a specific type of relation in which each domain value, or input, leads to exactly one range value, or output. Function notation is a shorthand method for relating the input to the output in the form y=f(x)y=f(x). In table form, a function can be represented by ...
