5-11-10 Function Analysis Example Draw the graph shown below and calculate the root for Y1. Y1 = x(x + 2)(x - 2) Use the following V-Window settings. Xmin = -6.3, Xmax = 6.3, Xscale = 1 Ymin = -3.1, Ymax = 3.1, Yscale = 1 (initial defaults) Procedure 1 m GRAPH 2 !3(V-WIN)1(INIT)J 3(TYPE)1(Y=)v(v+c)(v-c)w 6(DRAW) 3 !5(G-SLV)1(ROOT) 5e e ... Result Screen # When analyzing a single graph, results appear as soon as you select an analysis function in step 3, so step 4 is not necessary. # Root, local maximum value, local minimum value, and y-intercept can be calculated for rectangular coordinate graphs and inequality graphs only. # Graph analysis is not possible for the graph whose function is the format X = constant. # The y-intercept is the point where the graph crosses the y-axis. 20050401
