Today we finished talking about quadratics, specifically about how they move, and how to find the equation using two points from a graph. If you were not in class you definitely need to get some notes from someone, but you can check out the examples on pages 131-134. We focused on finding the x-intercepts and solving for "a" in the equation f(x)= a (x-h)^2 + k.
Let me know if you are still confused (when you post your comment) and I will post some examples tonight.
Have a great week!
Coming up:
- HW pg. 135 #'s 36-42 even, 78, 79, and find the x-intercepts from last nights homework (14-24)
- Tomorrow we will look at using Matricies to solve quadratics
Posting for Points:
From the standard equation of a quadratic, what do h and k tell you?

the h and k are the x,y coordinates for the vertex of the parabola
x and y coordinates of vertex
x and y coordinates
of vertex.
