1. The problem statement, all variables and given/known data I have a problem where I am given the model: x(t) = 2.5 - 2t + 0.8t2 From this I have to determine the x vs t, v vs t, and a vs t graphs. I have to do this without plotting points. Specifically it says, "Draw the graphs by identifying and interpreting the parameters, not by plotting points." 2. Relevant equations None, I don't think, except y=Ax2+Bx+C 3. The attempt at a solution I wish I could say I have an attempt, but I honestly don't know what to do. What am I looking for? This is algebra based physics, so I can't simply use calculus. Just a little guidance would be awesome. Thank you so much for any help!
