Behavior of Functions at their Zeros
- A B Cron
As the graph of a function approaches real zeros, the behavior of the line changes in relation to how close the function is to the x-axis. if the multiplicity of the zero is 1 -- the graph crosses through its coordinate (c, 0) even -- the graph is tangent to the x-axis and bounces or turns at c odd > 1 -- the graph is tangent to the x-axis and crosses at (c,0)
You can move the individual sliders to view different situation which you may encounter. Challenge, move the sliders to demonstrate as many diffent situations which might occur in your studies.
