2. Type the following on the entry line, using spaces to separate the "and" operator:

3. Tap Enter to graph the function.
Finding Points of Interest on a Function Graph
The Graphs application helps you find zeros, minimums, maximums, intersections,
derivatives (dy/dx), or integrals. For Graphs defined as conic sections, you can also find
foci, directrix, and other points.
(CAS): You can also find the point of inflection.
Identifying Points of Interest by Dragging a Point
▶ To quickly identify maximums, minimums, and zeros, create a point on the graph
and then drag the point.
Temporary signposts appear as you drag through points of interest.
