The table is displayed using the specified values. Start Specified the starting value for the independent variable, x. Step Specified the incremental value for the independent variable, x. The step can be positive or negative, but cannot be zero. Auto The TI-30XS MultiView™ calculator automatically generates a series of values based on table start and table step. Ask-x Lets you build a table manually by entering specific values for the independent variable, x. ³ Problem Find the vertex of the parabola, y = x(36 - x) using a table of values. Reminder: The vertex of the parabola is the point on the line of symmetry of the parabola. ozD36 UzE< - 15 $ - 3 $ $ < After searching close to x = 18, the point (18, 324) appears to be the vertex of the parabola since it appears to be the turning point of the set of points of this function. To search closer to x = 18, change the Step value to see points closer to (18, 324). Copyright © 2006 Texas Instruments Incorporated 39
