Domain 1 X 3 Range 2 Y 7
Means that x can be every number smaller than 5.
Domain 1 x 3 range 2 y 7. The range is the set of all valid values. Using the interval notation we can also write the domain as oo oo range. Add to both sides of the equation. The range of a constant function color blue f x a is just color red a.
Here are some examples illustrating how to ask for the domain and range. In this case there is no real number that makes the expression undefined. The domain is all values of x that give real numbers as answers and that is everything except 0 since 1 0 is illegal the range is all the values of y that can be reached from real values of x. We have the function color red y f x 7.
X lies between or is equal to 3 and 8 2 x 0 means that x can be every number greater than or equal to 2 but smaller than 0. Find the domain and range y 1 x 2 set the denominator in equal to to find where the expression is undefined. Enter your queries using plain english. To avoid ambiguous queries make sure to use parentheses where necessary.
Find the domain and range y x 2 1. Domain and range tips for entering queries. The domain is all values of that make the expression defined. Find the domain and range y 3 x.
The domain of the expression is all real numbers except where the expression is undefined. Find the domain of 1 e 1 x 1 function domain. The range is the set of all valid values. Square root of cos x.
The range is the set of all valid values. Domain is r set of real numbers and range is the set of real numbers greater or equal than 7 domain is r set of real numbers range is the domain of inverse function x sqrt y 7 it must be y 7 0 y 7 therefore range is the set of real numbers greater or equal than 7. Means that x can be every number greater than or equal to 7. The graph of color blue f x 7 is given below.
The domain of the expression is all real numbers except where the expression is undefined. Domain of log x x 2 1 x 2 1 domain. Hence the domain is oo x oo. Even though they are represented differently the above are the same function and the domain of the function is x 2 3 5 6 8 and the range is y 4 8 2 9 3 this is how you can defined the domain and range for discrete functions.
The function has neither undefined points nor domain constraints.
