Example Graph the two functions shown below, and determine the point of intersection between Y1 and Y2. Y1 = x + 1, Y2 = x2 • You can calculate the point of intersection for rectangular coordinate graphs (Y=f(x) type) and inequality graphs (Y > f(x), Y < f(x), Y ≥ f(x) or Y ≤ f(x)) only. • Either of the following can cause poor accuracy or even make it impossible to obtain solutions. - When a solution is a point of tangency between two graphs - When a solution is an inflection point u To determine the coordinates for given points 1. Draw the graph. 2. Select the function you want to perform. !5(G-SOLVE)6(g)1(Y-CAL) ... y-coordinate for given x 6(g)2(X-CAL) ... x-coordinate for given y 3. If there are multiple graphs on the graph screen, one of them will start flashing. Use f and c to move the flashing to the graph you want to select and then press w. 4. Input the given x-coordinate value or y-coordinate value. Press w to calculate the corresponding y-coordinate value or x-coordinate value. Example Graph the two functions shown below and then determine the ycoordinate for x = 0.5 and the x-coordinate for y = 2.2 on graph Y2. Y1 = x + 1, Y2 = x(x + 2)(x - 2) • When there are multiple results for the above procedure, press e to calculate the next value. Pressing d returns to the previous value. • The X-CAL value cannot be obtained for a parametric function graph. 5-56
