In this video you will learn how to determine whether a function is even, odd or neither. You must substitute negative x into the function and simplify. If your answer is the same as the original function, then the original function is even. If your answer is the exact negative of the original function, then the original function is odd. If it is anything else at all, the original function is n...

In this video you will learn how to find the angle between a straight line and the positive direction of the x-axis. The gradient of a line is usually referred to as "rise over run", while tan of an angle is known as "opposite over adjacent". These two definitions are essentially the same, so we use a formula m=tan(x) where x is the angle you are required to find. In this particular example tho...

This video shows you how to factorise using two methods. The first method is grouping in pairs and the second method is a trinomial where the coefficient of x^2 is not one.

This video shows you how to find the maximal domain of a function. Even if you do not know the shape of the graph of the function, there are techniques you can use to figure out its maximal (or implied) domain.

In this video you will learn how to substitute both numbers and algebraic terms into a given function. Answers must be in simplified form.

This video shows you how to identify whether or not a set of ordered pairs is a function. In order to be a function, no two points are allowed to have the same x value.

This video shows you how to find the domain and range of a function. You are asked to sketch the graph of a linear function and state the domain and range.
