Unformatted text preview: Numerical representations- table of values, listing the input-output pairs for a function • Partial numerical representations - “part” of the complete values are listed in a table Diagrammatic representations (diagrams)- visual diagram of a function with domain D and range R , where an arrow shows that x produces y Ex: D R Symbolic representation- a formula Ex: f(x) = x 3 Graphical representation (graph)- visually pairs an x-input with a y-input. Ex: f(x) = x y Identifying Functions By definition of a function, we can determine if a relation is a function. Vertical Line Test- If every vertical line intersects a graph at no more than one point, then the graph represents a function. y Ex: (x-h) 2 + (y-k) 2 = r 2 2 3 4 4 9 16 x x...
