Assignment #2

-light blue


-light gray

-dark gray





For this assignment, I graphed several different graphs by changing the coefficient of xy in the above equations. When the coefficient of xy is zero we have a circle shown in light blue. When the coefficient is -1 (yellow) or 1 (green) it is the graph of an oval. When the these values range from -4 to 4, the graphs of these functions go from hyperbolas at the -4 and 4 to almost parrallel lines at -2 and 2. This is nice graph to show how the changing of only one value of a function can completely change the looks of graph. This uses a more creative way of showing students how the graphs change by changing these coefficients.
