Domain And Range In Discrete Mathematics

Does every function have a domain.

Domain and range in discrete mathematics.

Endgroup hmakholm left over monica nov 14 13 at 19 58. Domain describes all the independent values in a function. The above list of points being a relationship between certain x s and certain y s is a relation. Discrete functions are derived from sets of data which have gaps in them.

Discrete and continuous domains a discrete domain is a set of input values that consists of only certain numbers in an interval. 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. 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. A discrete domain can have a finite set of values that will work for the x.

Domain range and codomain. If someone could explain this question in detail so i can do some revision on it i d be grateful. All numbers from 1 to 5 2 1 0123456 sometimes the set of points that represent the solutions of an equation are. In the relation above the domain is 2 4 11 21 the range is is 5 31 11 3.

As such they are described by sets of ordered pairs x y the domain and range of these functions are described in brackets with each individual value listed. Integers from 1 to 5 2 1 0123456 a continuous domain is a set of input values that consists of all numbers in an interval. Usually it is assumed to be something like all numbers that will work. Relations are often represented using arrow charts connecting the domain and range elements.

The example given earlier in the lesson about the amount of rain each month is this kind of discrete domain. Yes but in simpler mathematics we never notice this because the domain is assumed. Find the domain codomain and range. The domain is all the x values and the range is all the y values to give the domain and the range i just list the values without duplication.

Range describes all the dependent values in a function. The domain of a function is all the possible input values for which the function is defined and the range is all possible output values.
