Quadratic

1. Equations

   • Vertex Form y=a(x-h) +k
     • vertex (h,k)
     • gives the stretch factor and the vertex
   • Factored Form y=a(x-s)(x-t)
     • gives the stretch factor by a
   • Standard Form y=ax+by+c
     • gives the stretch factor and the y intercept(c)

2. Transformation

   • a<0 reflection
   • 0<a<1 vertical compression
   • a>1 vertical stretch
   • h>0 horizontal translation right

3. involving the second and no higher power of an unknown quantity or variable.
