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.
I checked homework today so if you were not in class today you must show it to me tomorrow!
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?

oh hai,
the (h,k) ordered pair tells you the location of the vertex of the parabola in the standard form equation.
the vertex
the vertex
(h, k) is the location of the vertex
vertex
the vertex of the parabola
the vertex
