alg I Quadratics review guide

The quadratics test will have 10 problems on it.  They are:

4 solving quadratic equations
1 solving a system that has a quadratic equation in it
1 writing an equation from solutions
1 application involving a rocket's path
1 graphing a quadratic equation
1 writing an equation from a list of ordered pairs
1 short answer on how to solve a quadratic equation


I can't overstate how much you should learn those problems from the last 2 quizzes (which were essentially the same quiz twice).   make sure you can do every problem on them well.


Outside of the quiz, you can work on these problems

1.  graph the quadratic function:  y = x^2 - 12x + 20
2.  what are the solutions to the graph in problem #1
3.  find the highest point on graph of the function, y = -6x^2 + 24x -3
4.  Write the equation to a quadratic function that has solutions, x = 3, -5
5. Write a rule for the sequence (4, 6, 10, 16...).  What is the 15th term?
