Video lesson: Finding the intersection of two graphs on the TI-84

By Tech Powered Dad | September 7, 2010

In this video lesson, you’ll learn how to find the intersection of two graphs on the TI-84+ graphing calculator.

The two functions graphed here are a line and parabola, but you could use this same approach for the intersection of two lines, or virtually any functions the TI-84 can graph. It’s also certainly possible to have more than two functions graphed at a time. You just have to let the 84 know which two functions you are trying to find the intersection of. 

STEM careers are the future. Will you be ready?
