Special graphs
I dont understand graphing functions. How do you read a function graph and name its domain and range, if for part of the graph x is greater than 2 and for another part x is less than or equal to 2. Wouldnt that make the domain all real numbers? Im not sure if I'm describing function graphs or peicewise graphs or what, so can someone also tell me what I'm describing? The graph is broken up and at some ends there is an open circle and at other ends there is a closed circle. Help.

Your explaining a piecewise function where the overall domain is indeed all real numbers, but each part of the graph has its own domain. To make this graph you must put the first equation in the y1, then use the such that key to set the domain. Finally write the second equation in y2 and use the such that key to set its domain.
