In this article, we review how to graph quadratic functions. Looking for an introduction to parabolas? Check out this video.

For any input into the function, you have to be very clear that you're only going to get one output. Now, with that out of the way, let's think about this function that is defined graphically.

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! Power up your …

Using points to sketch an exponential graph The best way to graph exponential functions is to find a few points on the graph and to sketch the graph based on these points. To find a point on the graph, …

The graph changes in a complex way compared to just changing the value of "h" or "k" because now you have a different parent function with a fundamentally different transformation of the x variable.

The general form of an absolute value function is f (x)=a|x-h|+k. From this form, we can draw graphs. This article reviews how to draw the graphs of absolute value functions.

So I have a homework question telling me to graph the rational function y=1/x and explain what is useful to see on the calculator and what is challenging. I knew what is useful and said how you can see the …

I encourage you to pause this video, and figure out what are the x and y-intercepts for the graph that represents the solutions, all the xy pairs that satisfy this equation.

A piecewise function is a function that is defined in separate "pieces" or intervals. For each region or interval, the function may have a different equation or rule that describes it. We can graph a …

We can approximate the solutions to any equation by graphing both sides of the equation and looking for intersection points. If we have a graphing calculator, we can get a very good approximation of the …
