Chicken (game) respectively. The line in graph on the left shows the optimum probability of playing the escalated strategy for player Y as a function of "x". The line in the second graph shows the optimum probability of playing the escalated strategy for player X as a function of "y" (the axes have not been rotated, so the dependent variable is plotted on the abscissa, and the independent variable is plotted on the ordinate). The Nash equilibria are where the players' correspondences agree, i.e., cross. These are shown with points in the right hand graph. The best response mappings agree (i.e., cross)
Graph of a function continuous function the graph of such a function is a surface. The concept of the graph of a function is generalized to the graph of a relation. To test whether a graph of a relation represents a function of the first variable "x", one uses the vertical line test. To test whether a graph represents a function of the second variable "y", one uses the horizontal line test. If the function has an inverse, the graph of the inverse can be found by reflecting the graph of the original function over the line . In science, engineering, technology, finance, and
