Domain And Range Mapping Examples

What is the domain and range of a function.

Domain and range mapping examples. Solved example on mapping ques. Similarly the range is all real numbers except 0. In its simplest form the domain is all the values that go into a function and the range is all the values that come out.

The set of values points which a function can obtain. X 1 0 1. Draw the mapping diagram for the given relation.

F x 2 x 1 solution. Domain range and codomain. Values in the domain map onto values in the range.

Its range is a sub set of its codomain. Use the mapping diagram for the relation and determine whether 3 1 6 1 3 2 6 2 is a function or not. Mapping diagrams a function is a special type of relation in which each element of the domain is paired with exactly one element in the range.

A relation is a function if each element in the domain is paired with one and only one element in the range. Set the denominator equal to zero and solve for x. A mapping diagram consists of two parallel columns.

So if the age is 10 years the height is h 10 200 cm. For example the function has a domain that consists of the set of all real numbers and a range of all real numbers greater than or equal to zero. Since the function is undefined when x 1 therefore the domain is all real numbers except 1.
