Ch 9 tests are graded and in powerschool.
On Friday we covered new material: we learned about what the definitions of quadratic functions and quadratic equations are. We learned that we use the terms solutions, zeros and x-intercepts to all mean the same thing. We learned that quadratics may have two, one, or zero solutions. We saw how to identify the solutions from the graph and to check them to make sure they are solutions.
We also learned how to find the solutions from the equation (and to check them too).
THE ASSIGNMENT is p. 530, the a,b,c items following example #1 (check understanding) AND p. 531, 10 - 18, the even items.
