Domain ( Input ): 2, 4, 5, 7 Range ( Output ): 32, 59, 65, 69, 96

Write as a Relation (5, 13), (10, 25), (15, 34), (20, 43), (25, 52)

Relations can be represented in different ways -1 2 3 4 1 2 5

This makes sense, because as a single person growing up can have only one height at a given point in time.

4) input output Not a function because the input 4 has two 3 1 Question / Key Words Notes or Solutions to Problems Decide whether the relation is a function. If it is a function, give the domain and the range 4) input output Not a function because the input 4 has two different outputs. 3 1 2 6 3 4 8
