Agenda: 1. Warmup 2. Lesson: 1.1 Functions and the Coordinate Plane ________________________________ Warmup (When you finish, work with your neighbor to see if you have similar answers. I will be randomly asking for student responses.) Identify the function(s). ± ²³´ µ ³ ± ´³² µ ³ ± ²³¶ µ · ± ²³´ µ ³ ± ´³² µ ³ ± ¶³² µ · ________________________________ Lesson: 1.1 Functions and the Coordinate Plane Goal: Identify functions and relations, and determine excluded values Definitions of the Day (DOD) Relation: A set of ordered pairs. Domain: The inputs of a relation. (x values) Range: The outputs of a relation. (y values) Function: A relation in which each input has exactly one output.

Unformatted text preview: State the domain and range of the following relation. Is the relation a function? {(2,3), (3, -4), (4, 1), (1, 3)} {(4, 4), (-2, 3), (4, 2), (3, 4)} ____________________________________ Do you remember function notation? (Everything in green is not expected for you to write down) If ± ² ³ ´ µ ¶·¸ ¹ º»¼½ f(16) f( ¸ ¾ ) Ch_1 Page 2 ____________________________________ Excluded Values : Values that are excluded from the domain because they make the function undefined. Input value that makes a denominator equal to zero. 1. Input value that makes a square root ( ± ² ) less than zero. 2. You are looking for two things. Find the excluded values. f(x)= ³ ´ g(x)= ³´µ¶ ·´µ¸ h(x)= ± ¹ º ² Ch_1 Page 3...
