The calculator will redraw the graph specified by the box. From the graph screen, select F5 Math . The TI-92 calculator allows you to select a number of different math options. A few are listed below. Minimum and Maximum find a minimum and maximum point within an interval.
Intersection finds the intersection of two functions.
Inflection finds the inflection point of a curve. Tangent draws a tangent line at a point and displays its equation. Let's start by looking at the intersection of these two functions. Next, move the cursor to the Lower Bound x value i.e. move the cursor to a point on either curve to the left of the intersection point. Then specify the Upper Bound point by moving the cursor to the right of the intersection point.
