  ## Vertex
  
  Definition: The point at which the axis of symmetry intersects a parabola.
  
  ## Axis of Symmetry
  
  Definition: A line about which a quadratic function (parabola) is symmetric. The equation used to find the axis of symmetry is shown below.
  
  ## Maximum Value
  
  Definition: The y-coordinate of the vertex of the quadratic function
  
  f(x)=a^2 + bx + c, where a<0
  
  ## Minimum Value
  
  Definition: The y-coordinate of the vertex of the quadratic function
  
  f(x)=ax^2 + bx + c, where a>0
  
  ## Standard Form
  
  Definition: A quadratic equation written in the form: ax^2 + bx+ c=0, where a, b, and c are integers, and a cannot = 0
  
  ## Vertex Form
  
  Definition: A quadratic function in the form y= a(x-h)^2 + k, where (h,k) is the vertex of the parabola and x=h is its axis of symmetry.
  
  ## Intercept Form
  
  Definition: y=a(x-r1)(x-r2)
  
  ## Completing the Square
  
  Definition: All quadratic equations can be solved using the Square Root method Property by manipulating the equation until one side is a perfect square, which is called "completing the square". You are changing the equation from standard form to vertex form.
  
  Follow the Steps below to Complete the Square:
  
  1. Put () around ax^2 + bx
  
  2. Factor the a value from x^2 and x
  
  3. Take 1/2 the middle term and square it
  
  4. Add the number and it's opposite
  
  5. Factor perfect square trinomial
  
  6. Rewrite in the form y= a(x-h)^2 + k (which is vertex form)
