In this lesson, Professor John Zhu gives an introduction to the definitions and properties of functions. He tells you what the defintion is, the vertical line test, domain and range. He explains how to find the root or zeros, and the difference between odd and even functions, as well as increasing and decreasing functions.
Vertical line test: any vertical line passes a function only once
Finding roots: set equation = 0, then solve for x
Forms: graph, list, equation, function
Types: even, odd, increasing, decreasing
