NOTES

y=a(x-p)(x-g)
X Intersepts
  • Solve for a
  • Write a equation
  • Leave in form y=a(x-p)(x-g)
y=ax^2+bx+c
  • 3 pts/ 3 equations
  • Solve the system for a,b,c
  • Plug into equation y=ax^2+bx+c
y=a(x-h)^2+k
Vertex: (h,k)
Point: (x,y)
  • Solve for a
  • Use a,h,k
  • to write an equation y=a(x-h)^2+k
