What is a function?
A function relates to input, relationship and output.
This can be said that a function is a mathematical process that uniquely relates the value
of one variable to the value of one (or more) variables.
Definition 1.1.1 A function is a rule that assigns to each element x in a set D exactly one
element, called f x ( ) , in a set E .
The set D is called the domain of the function. The number f x ( ) is the value of
f at x and is read “ f of x ”. The range of f is the set of all possible values of f x ( ) as
varies throughout the domain.
If f is a function with domain D , then its graph is the set of ordered pairs
{( x f x x D , ( ) | ) ∈ } .
In other words, the graph of f consists of all points ( x y , ) in the coordinate plane such
that y f x = ( ) and x is in the domain of f . We can read the value of f x ( ) from the graph
as being the height of the graph above the point x .

Definition 1.1.1 A. Rule is a function that assigns to each element x in a SET D exactly one
element, Called FX (), in a SET E.
The SET Called D is the domain of the function. Number the FX () is the Value of
F at x and is read "F of x". The Range of F is the SET of all possible values ​​of FX () as
varies throughout the domain.
If F is a function with domain D, then its graph is the SET of ordered pairs
{(Xfxx D, () |) ∈}. .
In Other Words, the graph of F consists of all points (XY,) in the Plane coordinate such
that Yfx = () and x is in the domain of F. Can we read the Value of FX () from the graph
as being the height of the graph above the x Point.
