Even, Odd, or Neither Functions The Easy Way! - Graphs & Algebraically, Properties & Symmetr Teacherflix 3 Views • 2 years ago

This algebra 2 and precalculus video tutorial explains how to determine whether a function f is even, odd, or neither algebraically and using graphs. This video contains plenty of examples and practice problems using variables and constants. First, plug in -x into the equation and see if the sign changes. If all signs change, it's an odd function. If they all remain the same, then it's an even function. If some change while others do not, the function is neither even or odd. For graphs, even functions are symmetric about the y axis. For odd functions, the symmetry exists about the origin. For circles with even and odd properties, it does not pass the vertical line test and is therefore not a function.

Hypothesis Testing - Solving Problems With Proportions Teacherflix 9 Views • 2 years ago

This statistics video tutorial explains how to solve hypothesis testing problems with proportions. It explains how to calculate the sample proportion and the z-test statistic and how to compare that with the critical values in order to determine whether or not if you should accept or reject the null hypothesis at a specified confidence level or significance level.

Financial Literacy—Making a Budget | Learn how to create a budget Teacherflix 10 Views • 2 years ago

As we discussed in the introduction video to this series, making a budget to balance your finances is a great way to ensure you have money for the things you want. Financial Literacy—Making a Budget explains how to create a budget based on your income and expenses. This will help your kids learn how to use a spending plan in order to use their money wisely.

Budgeting is a great skill to have that will help you learn how to save for something you want to buy. A budget is a spending plan to based on your income and expenses. In other words, it estimates how much money your earn and spend over time. Expenses can be either fixed or variable. Fixed expenses are the same every time you have to pay them. Variable expenses, well, vary.

To make a budget, you have to look are how much money your earn or receive as gifts (income). Then you look at your expenses. Subtracting your expenses from your income gives you the amount of money you have left over to spend on something you want. You must be careful to watch out for unexpected expenses though, which can put a dent in that budge of yours!

We hope you and your student(s) enjoyed learning about the difference between a need and a want! If you want even more information, head over to our website and download one of our many free lesson plans about financial literacy, full of activities, worksheets, and more!

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

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.

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!
