Given the function g(f(x)) = 2-x, you can find the domain as you would with any other function (i.e. it doesn't matter if it's composite). The output, however, has to be a real number. With this function, the domain is all real numbers. If you graph it, you see that the function is defined across the entire graph, wherever you choose to plot it.
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.
You do not graph range and domain: you can determine the range and domain of a graph. The domain is the set of all the x-values and the range is is the set of all the y-values that are used in the graph.
You can't.If f: D --> C where D is the domain of the function f and C is its codomain and D = Ø, then there are no d Є D. Therefore there are no c Є C : f(d) = c. Thus there are no ordered pairs (d, c) to graph.
Whatever you choose. The function, itself, imposes no restrictions on the domain and therefore it is up to the person using it to define the domain. Having defined the domain, the codomain, or range, is determined for you.

The highest point on a graph in the domain of a function is called the maximum or local maximum, depending on whether it is the highest point overall or within a specific interval. This point represents the maximum value of the function at that particular input, and it can be identified visually on the graph or mathematically through calculus by finding where the derivative is zero or undefined and confirming it as a maximum through further analysis. In a continuous function, a maximum may occur at the endpoints of the domain or at critical points within the interval.
Find the range of a function by substituting the highest domain possible and the lowest domain possible into the function. There, you will find the highest and lowest range. Then, you should check all the possible cases in the function where a number could be divided by 0 or a negative number could be square rooted. Remove these numbers from the range. A good way to check to see if you have the correct range is to graph the function (within the domain, of course).

The lowest point on a graph in the domain of the function is called the "minimum" or "global minimum" if it is the lowest point overall. If the lowest point is only the lowest within a certain interval, it may be referred to as a "local minimum." These points represent the values of the function where it attains its least value in the specified context.
To determine the domain of a function from its graph, examine the horizontal extent of the graph. Identify all the x-values for which there are corresponding y-values. If there are any breaks, holes, or vertical asymptotes in the graph, those x-values are excluded from the domain. The domain can then be expressed in interval notation, indicating any restrictions found.
The practical domain is the domain by simply looking at the function. Whereas the mathematical domain is the domain based on the graph.
Graph each "piece" of the function separately, on the given domain.
there is no graph... but most chance it's all real numbers
