SWBAT: Graph absolute value functions Lesson 6-10 Do Now: Work with a partner. Use a graphing calculator to match each absolute value function with its graph. 1 SWBAT: Graph absolute value functions Lesson 6-10 Graphing Absolute Value Functions Using a Graphing Calculator 1) Graph the parent function f ( x) x . The domain is the set of real number. x y= (x, y) a) What is the domain of f. d) What is f(3) = __________ b) What is the range of f. e) What is f(-2) = __________ c) For what value(s) of x is f(x)= 4? 2) Graph f ( x) x 4 . The domain is the set of real number. x y= (x, y) a) Write the domain as an inequality of f. c) What is f(3) = __________ b) Write the range as an inequality of f. d) What is f(-2) = __________ 2 SWBAT: Graph absolute value functions Lesson 6-10 3) Graph f ( x) x 4 . x y= (x, y) a) Write the domain as an inequality of f. c) What is f(3) = __________ b) Write the range as an inequality of f. d) What is f(-2) = __________ How do the values of a, h, and k affect the graph of the absolute value function ( ) = | − ℎ | + 3 SWBAT: Graph absolute value functions Lesson 6-10 4) Graph f ( x) x . What happened to this graph? 5) Application Problem MODELING WITH MATHEMATIC S The number of pairs of shoes sold s (in thousands) increases and then decreases as described by the function s(t) = −2 ∣ t − 15 ∣ + 50, where t is the time (in weeks). a. Graph the function. b. What is the greatest number of pairs of shoes sold in 1 week? 4 SWBAT: Graph absolute value functions Lesson 6-10 Summary 5 SWBAT: Graph absolute value functions Lesson 6-10 LESSON PRACTICE 6 SWBAT: Graph absolute value functions Lesson 6-10 LESSON PRACTICE 7 SWBAT: Graph absolute value functions Lesson 6-10 LESSON PRACTICE 8
