👉 Learn how to determine if a function is even or odd. A function is even if the graph of the function is symmetrical about the y-axis, or a function is even if f(x) = f(-x). A function is odd if the graph of the function is symmetrical...

👉 Learn all about the Limit. In this playlist, we will explore how to evaluate the limit of an equation, piecewise function, table and graph. We will explore continuity as well as discontinuities such as holes, asymptotes and jumps and...

👉 Learn how to solve quadratic equations using the quadratic formula. A quadratic equation is an equation whose highest power on its variable(s) is 2. The quadratic formula is a formula which can be used to find the roots of (solve) a...

👉Learn how to solve quadratic equations using the square root method. It is important to understand that not all quadratics have to be solved using factoring or quadratic formula. When we only have one variable but it is squared we can...

👉Learn how to solve a quadratic equation by factoring out the GCF. When factoring out the GCF from an equation we will be looking for what the terms have in common. This method is very useful for quadratic equations that does not have...

The video lecture focuses on understanding and sketching cubic functions that cannot be completely factorized. The speaker starts by reviewing the general shape of a cubic function and explaining how to identify different factorized...

The Diamond Model by Michael Porter is a renowned piece of work which helps us understand National Competitive Advantage. This means it helps us understand why certain countries are renowned for certain types of industries. We use mini...

👉 Learn how to find all the zeros of a polynomial given one rational zero. A polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. The zeros of a...

This program introduces the idea of the inheritance of traits. Attention is given to some of the fascinating features which are heredity-based not only in humans, but also in other plants and animals. The work of the father of modern...

In this video, the teacher explains how to graph a polynomial by finding the X-intercepts. They demonstrate the process step-by-step and emphasize the importance of testing intervals to determine the sign of the graph.

Learn how to multiply/divide rational expressions. A rational expression is an expression in the form of a fraction, usually having variable(s) in the denominator. Recall that to multiply two fractions, we multiply the numerators...

Learn how to divide rational expressions. A rational expression is an expression in the form of a fraction, usually having variable(s) in the denominator. Recall that to divide by a fraction, we multiply by the reciprocal of the...

Learn how to graph horizontal ellipse which equation is in general form. A horizontal ellipse is an ellipse which major axis is horizontal. When the equation of an ellipse is written in the general form, we first rewrite it in standard...

👉 Learn how to find the value that makes a function continuous. When given a piecewise function which has a hole at some point or at some interval, we fill the hole at the point or over the interval by looking for the value of the...

In this lesson, students learn how to multiply numbers in scientific notation by using the property of exponents. They review the concept of multiplying powers with the same base and then apply it to numbers in scientific notation. The...

In episode 55, Charlie and Jordan explore the venomous relationship between rattlesnakes and squirrels and how it helps scientists better understand how these natural enemies have co-evolved. This research could open the door to better...

This video is a lecture presentation on biotic factors. The presenter defines biotic factors and explains how they can affect communities and ecosystems. The focus is on living factors, such as availability of food, arrival of new...

👉 Learn how to solve problems using percents. When solving problems with percents we will either convert the percents to decimal form or use proportions to solve. We will look to solve for the percent of change, the original price,...

In this video series I will show you how to apply the equality of exponents to solve an equation. When we look at a simple equation of two exponents with the same base we can understand that their powers must also be equal. We will use...

👉 Learn how to identify transformations of functions. Transformation of a function involves alterations to the graph of the parent function. The transformations can be dilations, translations (shifts), reflection, stretches, shrinks,...

Learn how to graph horizontal ellipse which equation is in general form. A horizontal ellipse is an ellipse which major axis is horizontal. When the equation of an ellipse is written in the general form, we first rewrite it in standard...
