Domain And Range Numbers

Y y 0 r indicates range.

Domain and range numbers. The range is all real values of x except 0. The graph of latex f x x 2 latex red has the same domain input values as the graph of latex f x frac 1 12 x 3 latex blue since all real numbers can be input values. When using set notation inequality symbols such as are used to describe the domain and range.

You can take a good guess at this point that it is the set of all positive real numbers based on looking at the graph. Since the function is undefined when x 1 therefore the domain is all real numbers except 1. Find the domain and range of the following function.

Domain and range graph. All real numbers except 0. Find the domain and range of a function with a table of values.

F x 2 x 1 solution. Putting it all together this statement can be read as the domain is the set of all x such that x is an element of all real numbers the range of f x x 2 in set notation is. However the range of the red graph is restricted to only latex f x geq0 latex or latex y latex values above or equal to latex 0.

X 1 0 1. Make a table of values on your graphing calculator see.
