What we're going to do in this video is start to think about how we describe position in one dimension as a function of time. So we could say our position, and we're gonna think about position on the x-axis as a function of time, and we could define it by some expression. Let's say in this situation, it is going to be our time to the third power minus three times our time squared plus five, and this is going to apply for our time being non-negative because the idea of negative time, at least for now, is a bit strange. So let's think about what this right over here is describing, and to help us do that, we could set up a little bit of a table to understand that depending on what time we are, let's say that time is in seconds, what is going to be our position along our x-axis? So at time equals zero, x of zero is just going to be five. At time one, you're gonna have one minus three plus five, so that is going to be, see, one minus three is negative two plus five is going to be, we're gonna be at position three, and then at time two, we are going to be at eight minus 12 plus five, so we're going to be at position one, and then at time t equals three, it's gonna be 27 minus 27 plus five. We're gonna be back at five, and so this can at least help us understand what's going on for the first three seconds.
