Unit 3: Standard Form

Learning Goals

  • I am able to solve Quadratic equations using the Quadratic formula
  • I am able to graph a parabola using 2 x-intercepts and the vertex
  • I am able to convert a Quadratic relation from standard form to vertex form ( completing the square)

Summary Of the Unit

  • Standard form= ax^2 + bx + c
  • the value of a gives you the shape and direction of opening
  • the value of c is the y-intercept
  • Solve using the quadratic formula, to get the x-intercepts
  • MAX or MIN? Complete the square to get vertex form
