    I have this Algebra H.W. that's due tomorrow but I forget most of it because it was from a while ago. If someone would be able to answer these questions I would GREATLY appreciate it!!!

    1. How do you find a linear function that fits two points?
    1b. What generalizations can you make?
    2.Find a rule for a, and c that will make the graph of the quadratic function y=ax^2+bx+c go through the point (0,-1)?
    3.Find a value for a,b and c that will make the graph go through the point (1,2)
    4.Is there a quadratic function whose graph goes through both (0,-1) and (1,2)? Is it unique? That is, is there more than one quadratic function that's goes through these points?
    5.Is there a quadratic function whose graph goes through (0,1),(1,2) and (3,9)? Is it unique?
    6. In general, if we start with three specific points, will there be a quadratic function whose graph goes through those points?What generalizations can you make? Explain your answers.



    Thanks!
