# 4: Introduction to the TI-84


• 4.1: Graphing with the TI-84
• 4.2: Finding zeros, maxima, and minima
In this section, we will show how to locate local maxima and minima of a function (peaks and valleys of its graph), and the intersection points of two graphs. Further we will be able to use the calculator to find the x -intercepts of a graph. The x -intercepts are commonly called zeros or roots of the function f. In other words, a zero of a function f is a number x for which f(x)=0.
