 This video is going to show you how to do some basic things in GeoGebra. So we want to put an equation, we want to graph an equation, so we come down here to input and we want to say that y is equal to, let's say we just have a whole bunch of factors. So x plus 5 and then x minus 4 and then we'll do one with an exponent so you can see what to do there. So x plus 1 and then outside the parentheses here, just like in web work, if you've used web work, it's just caret 2 for your exponent. So then we press enter, it'll show us a graph. And if you come up here to this, it says move the graphics, I want to move my graph so I can just move it however I want to, so I can see some things. Well, I want to look at this, I can see that it looks like I'm going to have some low points or minimums on my graph way down, it looks like it's going to be quite a bit down, so I need to change the window for this one. So you come up here to options and you go to settings and then we want to talk about our graphics. Now sometimes you have to play with this, but if you set this over to the side you can usually see kind of what's going on. The basic dimensions is really what I want. So I need it to be something much bigger than negative 6 and so I could need to come in here and say okay, let this be a little bit more than that and let's say we want it to be negative 200. Move my cursor anywhere else, it's going to change my graph and we can look at it and definitely we have what we need. Looks like we probably could have gone to maybe 150 or 160, I would like to make that a little bit less. So let's go in here again and we'll say 160. Now you look at this and you're saying wow, that grid is so small. How do we change that? Well, let's talk about the grid, a distance here. We have the Cartesian coordinate on the X, we're okay, but for the Y here let's say that that's every 10, not 110, 10. And then if we just move and back to our basic just to see, we see that we have a much nicer graph. I could also come in here and change. Maybe I don't have enough Ys now. So I could come back to the basic and I could say okay, X4 is not near big enough so let's say let's see Y max to be 50. And then you have a graph that you would like to use. So you can just close out of here. Now if you want to look at the properties of your line, you can just right click, click on your function and right click it, down here it says object properties. I like to go to style so that the line thickness is bigger so you can see it better. I used to go somewhere between 7 and 9. If you wanted to make a color graph, you can come in here to color and just pick the color that you want your line to be, choose that nice red. And then the basics here, one of the nice things is down here at the labels. You can turn the labels on and off, right now it's turned off, but I have all these options. I choose to do a label, I can name it, I could maybe give it the name function or I can give it a value. The value you can see up there will just give me what my factors were. Or I can give both the name and the value or I can give it a caption. Maybe I want to say line one, okay, just to see what that does. If I close it, I can see now that it's going to tell me that this is line one even though it's not a line. And it's going to, I've got that nice red curve. Maybe I don't like that caption. So I go back to objects, right click on the curve and get the objects. And I don't want that caption anymore. But I would like to have the name and the, which is the f function. And I would like to have the value so I can see it. So now I'm going to close and now I have my f of x function and it gives me the actual factors that, all right, and you want to copy and paste it, file, export. I want to export it to the clipboard and then I have a word file here. So I just control V, I'm going to sit in there. There's my graph and I can then see my nice graph. I can move it, oh usually you move it by just pressing enter. And then I can make it bigger or smaller, however you want to work with it.
