Today we spent a while reviewing the homework. Number 10 was pretty tough, but we found an easier way than guessing and checking to find the equation for a quadratic. We know that the equation for a quadratic is:
We found out that if you take half of the second difference from the table you get "a" in the equation and we reviewed that the "c" is the y-intercept. To find the "b" we take a point from the table and solve for the value of "b". This is a great new strategy to practice!
We spent the remainder of class doing a function sort (you can find it in the link below if you forgot it at school). You must finish it for homework. Remember every story has a matching equation and a matching graph. I look forward to seeing the finished product tomorrow.
