What is domain and range ?
Range and Domain. The domain of a function is the set of values that we are allowed to enter into our function. This set consists of the x values for a function like f. (x). The set of values that a function can accept as input is known as its range. The function outputs this list of values once we enter an x value.
The term "domain," which is specific to the internet, can apply to both the structure of the internet and the organization of a company's network resources. A domain is typically a sphere of knowledge or a control area.
Given ,
[tex]\{(3,-1),(3,0),(-1,3),(0,3)\}[/tex] Since there is no value of y for every value of x (3,-1),(3,0),(-1,3),(0,3)this relation is not a function.
[tex]\{(1,2),(3,4),(5,6),(7,8),(9,10)\}[/tex] Since there is one value of y for every value of x (1,2),(2,3),(3,4),(4,5),(5,6) this relation is a function.
