  1. 1/31 Adv. Alg Bell Ringer Grab today’s materials Look at the clipboard and take your new seat Begin Bell Ringer: Determine the type of function in the following 3 examples: y = 3(x – 2)2 + 4 y = 3x + 4 3. y = 3x2 + 2x – 7 Homework: 1/31 Vertex Form Indep. Prac.

  2. 1/31 News and Notes • Everyone has 100%: What will you do to keep it? • Perfection, Round 2 • Round 1 Winners: Donuts for 2nd and 8th Period! • Bathroom and Locker Passes • Hand in old, receive new • If there’s a problem with your new seat, please tell me after class TODAY.

  3. Today’s Goal • Review transformations of quadratic functions in order to easily find vertex. • (I’m checking notes today)

  4. Bell Ringer Review • 2 units right • 4 units up • Vertical Stretch by 3 (skinnier) • Who cares?

  5. Discover why this helps us. • With your partner: Complete the activity in your notes by following the guiding questions. • You will receive 10 points for having complete notes and a complete activity. • Before asking questions of Mr. C you have to have had a convo with your partner.

  6. Key Question #1 • What’s the vertex of y = (x – 3)2 – 2 ? (3, -2) • In general, the vertex of y = a(x – h)2 + k is: (h, k)

  7. Therefore,y = a(x – h)2 + kis called… • The Vertex Form of a Quadratic Function • Why? • Because we can find the vertex very easily!

  8. 1 together… • What’s the vertex of y = - ½ (x + 1)2 – 7 ? • (-1, -7) • Why is it -1?! • Need the value of x that makes the parentheses = 0.

  9. Now give the IP a shot! • You now have the rest of class to work on the Independent Practice! • What you don’t finish is due tomorrow.
