In this lesson, you will learn how to view functions as a set of ordered pairs where the output values are represented by f of x instead of y. The video also covers identifying zeros of a function, which occur when the output value is zero, and how to determine intervals of increase and decrease on a graph. Additionally, the lesson explains relative minimum and maximum points on a graph and how to identify them.
Overview of functions - Zeros, increasing, and decreasing
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
