GRAPHINGAlgebraSummaryThe important information in this chapter is summarized below.Graphing SummaryOrdinate - x-coordinateAbscissa - y-coordinateCartesian Coordinate System- Rectangular Coordinate System- Divided into four quadrants by x- and y-axisLogarithmic Coordinate System- One or both of the scales are divided logarithmically- Semi-log graphs contain linear x-axis and logarithmic y-axis- Log-log graphs contain logarithmic x- and y-axisLinear functions are usually plotted on Cartesian coordinate graph.Exponential functions (y = ex) are usually plotted on semi-log graphs toprovide a straight line instead of the resulting curve placed on a Cartesiancoordinate graph.Power functions (Y = ax2, y = ax3, etc.) are usually plotted on log-loggraphs.MA-02 Page 84 Rev. 0
