Objectives: In this tutorial, we investigate different ways to graphically and numerically find roots of functions and points of intersection of two
graphs of functions.
After working through these materials, the student with a graphing calculator should be able
- to find graphically and numerically an approximation to the coordinates of points of intersection of graphs of functions;
- to find graphically and numerically the roots of a function.
Modules:
- Zooming in
- Discussion
