GRAPHING CALCULATOR STEPS
Finding the Vertex
1. Graph the quadratic equation by typing the equation into y=.
2. Check and adjust the window so the graph can be seen.
3. Press the calc key (2
trace).
nd
4. Press 3:Minimum or 4:Maximum.
5. Move the cursor to a position that is left (bound) of the vertex and press enter
6. Move the cursor to a position that is right (bound) of the vertex and press enter
7. Press enter for guess?
8. The coordinates of the vertex will be displayed on the screen.
Graph the following quadratic equations. Find the vertex using any method included the
graphing calculator, and find four other points. Determine the type of x-intercepts (possible types:
two real, one real (double root), or two imaginary)
