  1. Parent Functions Bell Ringer copy on separate note paper, not Bell Ringer sheet; On Bell Ringer Sheet write: Parent Functions Key words:

  2. Chapter 1.2 Common Core Algebra 2 Objectives F-IF.5, F-BF.3 Identify parent functions from graphs and equations. Use parent functions to model real-world data and make estimates for unknown values.

  3. Example : Identifying Transformations of Parent Functions Identify the parent function for g from its function rule. Then graph g on your calculator and describe what transformation of the parent function it represents. g(x) = x – 3 x has what power ? What is the parent function ?

  4. Example : Identifying Transformations of Parent Functions Identify the parent function for g from its function rule. Then graph on your calculator and describe what transformation of the parent function it represents. g(x) = x2 + 5 x has a power of ? Parent function ? Domain ? Range ?

  5. Example Identify the parent function for g from its function rule. Then graph on your calculator and describe what transformation of the parent function it represents. g(x) = x3 + 2 x has a power of ? Parent function ?

  6. Battle Ship Algebra 2 version Students work in pairs, I will pick teams. One student in each pair should choose a function belonging to a family described in this lesson. This student should give his or her partner the coordinates of points that lie on the function’s graph. The partner should plot the points until her or she can determine the parent function. The given equation is not the parent function; it is a translation of the parent. Complete one, then switch positions.

  7. Exit question Identify the parent function for g from its function rule. Then graph g on your calculator and describe what transformation of the parent function it represents. g(x) = x2 – 7 Domain ? Range ?

  8. Bell Ringer Identify the parent function for g from its function rule. Then graph g on your calculator and describe what transformation of the parent function it represents. Include the domain and range. g(x) = 2x2+5

  9. Exit question Stacy earns $7.50 per hour. Graph the relationship from hours to amount earned and identify which parent function best describes it. Then use the graph to estimate how many hours it would take Stacy to earn $60. Answer only required
