I do Math through a highschool, but I use Khan Academy to get extra practice in the subjects in my course. It says "graphing a function rule", but I can't find anything similar here, to what it's teaching me on the course.
I have a picture of an example of what it is below. If you can send me a link to any videos/exercises similar to the example I gave, that would be great, because I can't seem to find anything.
Hope this isn't too much trouble,
