– WE WANT TO DETERMINE THE EQUATION OF THE QUADRATIC FUNCTION FROM THE GRAPH. WE ALSO WANT TO GIVE THE FUNCTION IN GENERAL FORM. REMEMBER GENERAL FORM OF A QUADRATIC FUNCTION IS F OF X=AX/SQUARED + BX + C. BUT TO FIND THIS FORM OF THE FUNCTION, WE’RE ACTUALLY GOING TO USE THE STANDARD FORM…

## Probability for Independent and Dependent Events 128-1.5

This video is provided as supplementary material for courses taught at Howard Community College and in this video I want to talk about probability for independent and dependent events. So here’s our example. I’ve got some pieces that I took from a Scrabble game. There are two squares and they have A’s on them. And…

## Functions Part 1

>>In this video I will be introducing the idea of what a relation and a function is. Both of these could be represented in different ways. For instance we could have a table of values, a graph, a formula; this is the most common way you’ll see. Words where it’s described, a set of ordered…

## Graphing Absolute Value Functions as Piecewise Functions 3 Examples

Bam Mr. Tarrou In this lesson we’re going to be taking a look at graphing three examples of absolute value functions as piecewise functions when you go into calculus this may be very well be an algebra 2 honors course or precalculus course when you step into calculus it’s going to be important that we…

## Ex 1: Key Characteristics of the Graph of a Quadratic Function (Opens Up)

– IN THIS PROBLEM WE’RE GIVEN THE GRAPH OF A QUADRATIC FUNCTION AND ASKED TO FIND ALL THE KEY CHARACTERISTICS. WE FIRST WANT TO START BY FINDING THE DOMAIN OF THE FUNCTION. REMEMBER THE DOMAIN IS A SET OF ALL POSSIBLE X VALUES OR INPUTS AND SINCE THE X AXIS IS THE HORIZONTAL AXIS HERE,…

## Algebra 15 – Functions

Hello. I’m Professor Von Schmohawk and welcome to Why U. In the last several lectures we looked at some examples of binary relations. These binary relations can illustrate mathematical relationships or data measurements from the real world. In this lecture, we will introduce a special type of binary relation which we will often encounter in…

## ❖ One to One and Onto Functions (Isomorphisms) ❖

Alright, so in this video. I want to talk about what are known as one-to-one and onto functions So eventually I’m going to start talking about this in a linear Algebra setting we’ll talk about vectors and linear transformations But at the beginning, you know this is something I’m going to do it a little…

## Composite Functions

– WELCOME TO A VIDEO ON COMPOSITE FUNCTIONS. A COMPOSITE FUNCTION CAN BE THOUGHT OF AS A COMBINATION OF TWO FUNCTIONS. ONE WAY TO ILLUSTRATE THIS WOULD BE TO USE A CONVEYOR BELT WHERE WE HAVE AN INITIAL INPUT OF, LET’S SAY, 3, ONE WAY TO ILLUSTRATE THIS WOULD BE TO USE A CONVEYOR BELT…
