Week 8- Quadratics

One thing we were introduced to this week was Standard Form. This is my favorite from when graphing because it tell you so much about the graph. Standard form looks like: $latex\ y= a(x-p)^2 +q   Where a cannot equal 0

ex. Y=1(x-1)^2 +2

The A value tell you which way the parabola open (positive up/ negative down) It also tells you the stretch value (it its bigger than 1 it stretches if its smaller than one it compresses or gets wider)

The p and q value are the coordinates for the vertex.

The p value gives you the axis of symmetry.

Something that the General form tells that the Standard form does not is that that the general form tells you the y-int.
