Correcting Misplaced Modifiers

By WarnerJordanEducation

This video describes the function of modifiers in a sentence. Then, it shows how to identify correct often humorous cases of misplaced modifiers.

Algebra Applications: Quadratic Functions

Forensics. The distance a car travels even after the brakes are applied can be described through a quadratic function. But there is also the reaction time, the split second before the brakes are applied. The total distance is known as the stopping distance and this segment analyzes the quadratic function. This is an equation that can be used by accident investigators.

Using Adverbs Correctly

By WarnerJordanEducation

This video first reviews the function of adjectives to modify nouns and follow linking verbs. It then explains the use of adverbs to describe verbs, adjectives, and other adverbs. Each use comes with examples and explanations

Graphing Quadratic Functions - Example 1

By PatrickJMT

Watch this video to learn how to graph a quadratic function of the form ax2 +bx + c, where a, b, and c are constants (and a≠0). All functions of this form describe the graph of a parabola (u-shape) that either opens upward or downward. To graph a quadratic function: Consider the leading coefficient (the value of a) to determine if the parabola opens upward (postive a) or downward (negative a) Calculate the vertex of the parabola from a and b. The vertex is the highest or lowest point of the parabola. Find the x-intercept(s) (zeros) Find the y-intercept. (Found by plugging x=0 into the function).

Algebra Applications: Exponential Functions

By Media4Math

In this episode of Algebra Applications, students explore earthquakes using exponential models. In particular, students analyze the earthquake that struck the Sichuan Province in China in 2008, months before the Beijing Olympics. This dramatic, real-world example allows students to apply their understanding of exponential functions and their inverses, along with data analysis and periodic function analysis. Segments include: What is an earthquake? The basic definition of an exponential function is shown in the intensity function for an earthquake. Students analyze data and perform an exponential regression based on data from the Sichuan earthquake. What is the difference between earthquake intensity and magnitude? An exponential model describes the intensity of an earthquake, while a logarithmic model describes the magnitude of an earthquake. In the process students learn about the inverse of an exponential function. How is earthquake magnitude measured? An earthquake is an example of a seismic wave. A wave can be modeled with a trigonometric function. Using the TI-Nspire, students link the amplitude to an exponential function to analyze the dramatic increase in intensity resulting from minor changes to magnitude.

1.3 How to determine the domain and range of three graphs - domain and range

By Mr. McLogan's Math Channel

http://www.freemathvideos.com n this math tutorial I describe how to find the domain of a function by determining when the bottom of a rational function is zero and when the root is negative. I also might look at the graph and determine the intervals for the domain of the function. For a rational expression we set the bottom of the rational expression to zero and solve for x. For a function with an even root we set the radicand greater than or equal to zero and solve for x. 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 exaclty 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

Proof that rational times irrational is irrational | Algebra I | Khan Academy

By Khan Academy

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
