For instance the domain of cosine is the set of all real numbers while the domain of the square root consists only of numbers greater than or equal to 0 ignoring complex numbers in both cases.
Domain math all real numbers. The range is also all real numbers except zero. Division by zero is not allowed. The domain and range are all real numbers because at some point the x and y values will be every real number.
One way to determine this is to look at it graphically. Algebraically the domain is the set of all real numbers except zero since the denominator can not equal zero. The line and function to the left has a domain and range of all real numbers because as the arrows indicate the graph goes on forever both negatively and positively.
We can see that the graph is discontinuous at latex x 0 latex indicating that the domain is all numbers other than latex x 0 latex. Therefore this statement can be. 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.
Y y 0 r indicates range.
