# 6 1 Practice Operations On Functions

The concept of operations on functions is one of the most important topics in mathematics. It involves combining two functions to form a new function. There are several different operations that can be performed on functions, including addition, subtraction, multiplication, division, and composition. Each of these operations has its own rules and properties, and understanding them is key to success in mathematics. In this article, we will look at 6.1 practice operations on functions. The addition operation is one of the most basic operations on functions. It involves adding two functions together to form a new function. When adding two functions, the domain and range of the resulting function are the same as the domain and range of the original functions. For example, if two functions f(x) and g(x) are added together, the resulting function will be f(x) + g(x). The domain and range of this new function will be the same as the domain and range of f(x) and g(x).

## Subtracting Two Functions The subtraction operation involves subtracting two functions from each other. For example, if two functions f(x) and g(x) are subtracted from each other, the resulting function will be f(x) – g(x). The domain and range of the resulting function will be the same as the domain and range of the original functions. It is important to note that when subtracting two functions, the order in which they are subtracted matters. If the order is reversed, the result will be different.

## Multiplying Two Functions The multiplication operation involves multiplying two functions together. For example, if two functions f(x) and g(x) are multiplied together, the resulting function will be f(x) x g(x). The domain and range of the resulting function will be the same as the domain and range of the original functions. It is important to note that when multiplying two functions, the order in which they are multiplied matters. If the order is reversed, the result will be different.

## Dividing Two Functions The division operation involves dividing two functions. For example, if two functions f(x) and g(x) are divided, the resulting function will be f(x) ÷ g(x). The domain and range of the resulting function will be the same as the domain and range of the original functions. It is important to note that when dividing two functions, the order in which they are divided matters. If the order is reversed, the result will be different.

## Composing Two Functions The composition operation involves combining two functions together to form a single new function. For example, if two functions f(x) and g(x) are composed together, the resulting function will be f(g(x)). The domain and range of the resulting function will be the same as the domain and range of the original functions. It is important to note that when composing two functions, the order in which they are composed matters. If the order is reversed, the result will be different.
