Domain Math Example

Interval notation and set notation.

Domain math example. When finding the domain remember. However the most common example of a limited domain is probably the divide by zero issue. Domain of a relation is the set of all x coordinates of the ordered pairs of that relation.

By taking an example of a coin stamping machine we can illustrate the meaning of a function as follows. Before getting into the topic of domain and range let s briefly describe what a function is. Domain of the relation 3 4 9 8 4 5 is 3 4 9.

The domain is the set of all possible x values which will make the function work and will output real y values. In mathematics a function can be compared to a machine that generates some output in correlation to a given input. A simple function like f x x 2 can have the domain what goes in of just the counting numbers 1 2 3 and the range will then be the set 1 4 9 and another function g x x 2 can have the domain of integers 3 2 1 0 1 2 3 in which case the range is the set 0 1 4 9.

In the example above the range of f x f x is set b. How to figure the domain range of ordered pairs. Here is the graph of y sqrt x 4.

The denominator bottom of a fraction cannot be zero. References to complexity and mode refer to the overall difficulty of the problems as they appear in the main program. 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.

The number under a square root sign must be positive in this section. When asked to find the domain of a function start with the easy stuff. Let s take another example.
