Find the Domain and Range from a Graph

Learn how to find domain,range, and if a line is a function from a graph. Follow these guidelines Domain = X Values Read from left to right [ and ] for closed and straight lines ( and ) for open and positive and negative infiniti Range = Y values Read from bottom to top [ and ] for closed and straight lines ( and ) for open and positive and negative infiniti Function : A relation where x does not repeat I'm working through the whole Algebra 1 course.
