2016.11.28 #### Linear Functions

In this video, Mahalo math expert Allison Moffett explains linear equations. Functions are just equations that express a specific relationship between two variables. To express this algebraically, write f(x)=ax+b. You may think that this looks a lot like slope-intercept form (y=mx+b), and you'd be right. Slope-intercept form is an example of a linear function. Let's say you have the function f(x)=7x-2, and you want to evaluate it at x=8. All you need to do is plug in an 8 wherever you see an x...

2017.09.08 #### 06 - What is a Function in Math? (Learn Function Definition, Domain & Range in Algebra)

Get more lessons like this at 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 se...

2018.12.19 #### Finding the inverse of a function

Learn how to find the inverse of a linear function. A linear function is a function whose highest exponent in the variable(s) is 1. The inverse of a function is a function which reverses the "effect" of the original function. One important property of the inverse of a function is that when the inverse of a function is made the argument (input) of a function, the result is x. Given a function, say f(x), to find the inverse of the function, we first change f(x) to y. Next, we change all x to y an...
