Question

what is domain range give examples
​

Answer 1

Answer:

The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} . Note that the domain elements 1 and 2 are associated with more than one range elements, so this is not a function.

Answer 2

Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Step-by-step explanation:

Example: When the function f(x)=x2 f ( x ) = x 2 is given and the values x=1,2,3,4,... x = 1 , 2 , 3 , 4 , . . . , then the domain is simply the set of natural numbers and the output values are called the range.
