Algebra 1 Unit 2 Day 1 Notes: Multiple Representations of Relations and FunctionsTarget: I can represent relations and functions using coordinates, tables, graphs, and mappings.I can also determine if a graphed relation is a function by using the vertical line test.A Relation is a mapping, or a pairing, of inputvalues with output values.A relation can be represented in the following ways:CoordinatesTable(-2,2)XY(-2,-2)-22(0,1)-2-2(3,1)0131GraphMappingy2-2I2I0-3IExample: Given the relation {(-4, 3), (3,2), (2, -1), (0, -3)}.
