Step-by-Step Examples
Example 1: Graph a Quadratic Function
Want to graph y = x² + 2x - 3? Here's how:
- 1Press Y= to open the function editor.
- 2Type X² + 2X - 3 (use the X,T,θ,n key for X).
- 3Press GRAPH to see the curve.
- 4Press WINDOW to adjust the view (try Xmin=-10, Xmax=10, Ymin=-10, Ymax=10).
- 5Press TRACE to explore points on the graph. Cool, right?
