Web based Graphing Calculator
Here is a web based graphing calculator that you can use to help you gain a better understanding of the functions that we will be studying this year and to help you with your homework.
Notice that it is also possible to find the intersection of two graphs using the intersection tab.
If you are trying to find the roots of a function make the second function equal 0, y = 0, then find the intersection. Remember that y =0 is actually the x axis and that is where the roots are found.
Happy graphing! :-)
