Rearranging to solve for the variable you want to measure, you get a function (as long as there's not multiple outputs for any input)! Functions involve anything with an independent and …

Many functions are equations. But, they don't have to be. If you have a set of ordered pairs where each x-value relates to only one y-value, then you have a function. For example: { (2,5); (3,8); …

So the question here, is this a function? And for it to be a function for any member of the domain, you have to know what it's going to map to. It can only map to one member of the range. So …

About this unit A function is like a machine that takes an input and gives an output. Let's explore how we can graph, analyze, and create different types of functions. Unit guides are here! …

Finally, let's finish this process by plotting the y -intercept (0, 8) and filling in the gaps with a smooth, continuous curve. While we don't know exactly where the turning points are, we still …

The intuition works like this: We sometimes think about functions as an input and an output. For example, we take a value, called x, and that is what we put into the function. Then the function …

Even functions are symmetrical about the y-axis: f (x)=f (-x). Odd functions are symmetrical about the x- and y-axis: f (x)=-f (-x). Let's use these definitions to determine if a function given as a …

Learn how to build a mapping diagram for a finite function, and how to use this diagram to determine if the function is invertible. An invertible function has a one-to-one mapping between …

I think to some level, it might be confusing, because it's such a simple idea. Each of these values can only have one height associated with it. That's what makes it a function. If you had more …

If we get an expression that is equivalent to f (x), we have an even function; if we get an expression that is equivalent to -f (x), we have an odd function; and if neither happens, it is …
