Domain and Range

[Anthony.G]

The instructions are to write the domain and range for each of the graphs. I am not sure how to find this and or write this in the form it is written (circled in red). The teacher told us to write this down for example. Getting back to me would be awesome

Thank you

P.S. Hopefully you can enlarge the picture if not this is the link------> file:///C:/Users/Anthony/Downloads/2015-02-03%2019.34.04%20(1).jpg

Can you at least tell us what you think the domain and range of a function is?

Here is a big hint. Do the following for each graph. Imagine moving each and every point vertically to the x-axis. How would you describe the points that are now on the x-axis. Will these points be the domain or range or ...?

Now imagine moving each and every point on the graph horizontally to the y-axis. How would you describe the points that are now on the y-axis. Will these points be the domain or range or ...?
