Quadratic Graph

• What is the completed square form of a quadratic equation?

  k(x+p)² + q
• How is the value of p or q determined in the completed square form?

  By substituting the turning point
• What is the next step after finding p or q from the turning point?

  Substitute another point to find k
• What happens to the equation if the turning point is (0,0)?

  The equation simplifies to y = k(x)²
• What are the steps to find the equation of a quadratic graph from a turning point?

  1. Use the completed square form: k(x+p)² + q
  2. Substitute the turning point to find p or q
  3. Substitute another point to find k
  4. If the turning point is (0,0), simplify to y = k(x)²
• What is the significance of the turning point in finding the quadratic equation?

  It helps determine p and q values
• Why are p and q considered useless when the turning point is (0,0)?

  Because they do not affect the equation
