Parabola lab day 3

  1. 1. Sept 5th Learning outcome: To discover what happens to a parabola’s graph when you change the numbers in the equation?  Launch:  2. Graph each equation without making a table or using a calculator. What are your strategies?  a. y = (x-3)2 – 5 b. y = 0.5 (x-3)2 + 2
  2. 2. Explore Standard Form  2. Now we are going to look at quadratics in standard form y = ax2 +bx + c  a. What is the orientation of y = 2x2 +4x - 30? (up or down facing)  b. What is the stretch factor of y = 2x2 +4x - 30? C. Can you look at y = 2x2 +4x -30 and figure out the vertex?
  3. 3. Explore: Standard Form  3. Now we are going to look at quadratics in standard form y = ax2 +bx + c  a. What is the orientation of y = 2x2 +4x - 30? (up or down facing)  b. What is the stretch factor of y = 2x2 +4x - 30? C. Can you look at y = 2x2 +4x -30 and figure out the vertex?
  4. 4. Notes: Quadratic
  5. 5. Explore: Math Models
  6. 6. Explore: Quadratic models  Sketch the path of the jackrabbit on your paper. Choose where to place the x- and y- axes in your diagram so they make sense and make the problem easier. Label as many points as you can on your sketch. a. What point on your graph can tell you about the values of h and k in the equation? Write those values in a general equation b. With your group, find a strategy to find the value of a. Will any points on the diagram help?
