Domain Math Example Equation. For example if a person has 100 to spend he or she would need to express the interval that is more than 0 and less than or equal to 100 and write latex left 0 text 100 right latex. X 0 x 0 the domain is all values of x x that make the expression defined.
When the function f x x2 is given the values x 1 2 3 then the domain is simply those values 1 2 3. For example the domain of f x x is all real numbers and the domain of g x 1 x is all real numbers except for x 0. Therefore the function is zero if x 3 or x 2.
4 6 in inequality notation the domain is written as.
Solution to example 1. Interval notation and set notation. The function f x x2 has a domain of all real numbers x can be anything and a range that is greater than or equal to zero. F x x 2.
