The allowable values of x are called the "domain", and the resultant set of possible y values are called the "range".
the domains
y = x This is a line and a function. Function values are y values.
X > 9
First column, of x values, is the domain of x - whatever that may be. Second column, of function values is always 3.
Domain: All Possible "x" values Range: All possible "y" values
Its called a varible.
The Input or X values are called the Domain.
the domains
The term that describes the set of all possible values for a function is called the "range." The range includes all output values that the function can produce based on its domain (the set of all possible input values). In mathematical terms, if ( f: X \rightarrow Y ) is a function from set ( X ) to set ( Y ), then the range is a subset of ( Y ).
Domain is what you can plug into the function (possible x values for y=f(x) type functions) and range is the possible values you can get out (possible y values).
"Domain" means for what numbers the function is defined (the "input" to the function). For example, "x + 3" is defined for any value of "x", whereas "square root of x" is defined for non-negative "x". "Range" refers to the corresponding values calculated by the function - the "output" of the function. If you write a function as y = (some function of x), for example y = square root of x, then the domain is all possible values that "x" can have, whereas the range is all the possible values that "y" can have.
In algebra, the domain consists of all possible values for the x variable that could make the function work. The range is all of the possible values of the function, using each number in the domain.
A function, f, is usually a mapping from a set of input values. This set, whose elements are often denoted by x, is called the domain.A function, f, is usually a mapping from a set of input values.

y = x This is a line and a function. Function values are y values.
The domain of a function encompasses all of the possible inputs of that function. On a Cartesian graph, this would be the x axis. For example, the function y = 2x has a domain of all values of x. The function y = x/2x has a domain of all values except zero, because 2 times zero is zero, which makes the function unsolvable.
I cannot see the graph you are referring to. However, to determine the domain of a function, you need to identify all possible input values (x-values), while the range consists of all possible output values (y-values). If you provide more details about the function or its characteristics, I can help you determine the domain and range.
The domain of a function is the set of it's possible x values that will make the function work and output y values. In this case, it would be all the real numbers.
