All trigonometric functions are basically the trigonometric proportions of any given angle. For example, if we take the functions , , etc, we are considering these trigonometric proportions as functions. The domain and range of these trigonometric functions will...

The domain of exponential functions is equal to all real numbers since we have no restrictions with the values that x can take. The range of exponential functions is equal to the values above or below the horizontal asymptote. Here, we will see in detail how to find...

The domain of linear functions is equal to the entire set of real numbers of x. This is because we do not have any restrictions on the values of x. Similarly, the range of linear functions is also the entire set of real numbers in y. Here, we will look at more details...

In this article, we will learn how to find the domain and range of a rational function either by using its graph or by using definite algebraic rules. We will start by doing a brief review of what domain and range mean. Then, we will look at the methods used to find...

Graphs of functions can be used to determine the domain and range. The graphs give us an idea of which values of x and which values of y are being taken. Many times this can be enough to fully determine the domain and range. However, there will be...
