Domain example in math. The number under a square root sign must be positive in this section. The denominator bottom of a fraction cannot be zero. The domain and range of a function is all the possible values of the independent variable x for which y is defined.

Here is the graph of y sqrt x 4. The range of a function is all the possible values of the dependent variable y. For the function y 3 x 1 all real numbers work except for 1.

The lands we are situated on are covered by the williams treaties and are the traditional territory of the mississaugas a branch of the greater anishinaabeg nation including algonquin ojibway odawa and pottawatomi. In the relation above the domain is 2 4 11 21 the range is is 5 31 11 3. An example in which the domain is not all real numbers is when a function results in an undefined number.

The example below shows two different ways that a function can be represented. It is the set x in the notation f. Relations are often represented using arrow charts connecting the domain and range elements.

If the domain and range are all real numbers like in the example below we can use the double backed r to show that all real numbers are included in the domain and range. As a function table and as a set of coordinates. 3 1 1 5 2 5 0 0 2 3 it is very easy to find the domain and range of a cluster of points.

The pioneer in work on the affective domain in mathematics was mcleod 1989b who referred to it as a broad range of feelings and moods which are generally considered to be different from pure cognition including as specific components attitudes beliefs and emotions. What is the domain and range of the following relation. Sometimes such a ring is said to have the zero product property equivalently a domain is a ring in which 0 is the only left zero divisor or equivalently the only right zero divisor.
