FUNCTION | TYPES OF FUNCTION WITH EXAMPLES
Here you will learn what a function is in math, the definition of a function, and why they are important.
Functions have applications in algebra, calculus, science, and engineering. We first begin by describing a function as a mathematical machine that takes input numbers "x" and computes output numbers "f(x)".
We then describe the input numbers "x" as being the domain of the function, while the output numbers f(x) are the range of the function. We will plot several functions including linear functions, quadratic functions, cubic functions, and more.Learning about functions is critical in math, especially in Algebra. Many students struggle with the concept of what a function is and how to determine is a relation is a function. This video will explain in detail the foundation of what a function is in algebra to include how to evaluate a function and what the domain and range represent with respect to functions.
