What is the difference between the domain and the range?

Answer 1

Domain is the x-axis and range is the y-axis
The domain is all the x-values that a function that take on, and the range is all the y-values that it can be. For instance, if you were given a set of coordinates such as {(2,3), (4,1), and (-9,5)}, you domain would be (-9, 2, 3) for the x-values, and your range would be (1,3,5) for the y-values. If you have to find domain and range for a function, domain typically being found first, you must think of all the possible x-values that could satisfy that equation. If there is a square root, you must ensure that the values do not make that section of the equation negative, and in other cases you must make sure you do not divide by zero. You can then find the range by making a graph or a chart.
Domain is/are the value(s) which go under a rule (function of x) and the range is/are the value(s) you get out.
