0:24 y=2(x-9)^2 +3 The skeleton equation equals y=a(x-K)^2 +K

a=stretch h=left right shift,k=up down shift

1:55 What are the transformations of: y=-4/7(x)^2 -6

3:05 What if you are given descriptions and you have to write an equation? Once you write your descriptions you plug these into the vertex equation
