Determine who is right?
To do this, we simply test each sequence.
For Carlos:
When n = 1

When n = 2

<em>This is incorrect because the first and second term of the sequence are -10 and -4 not -4 and 2</em>
<em></em>
For Ana:
When n = 1

When n = 2

When n=3

When n = 4

Determine if a real life situation is a function or not
I will give 2 instances
(1) Students and their ID
The relationship is as follows:
Student 1 -----> ID-1
Student 2 -----> ID-2
Student 3 -----> ID-3
Student 4 -----> ID-4
---------
----
--
Student n -----> ID-n
The above is a function because every student has a unique student ID.
In fact, the relation is a one-on-one function because no two students will have the same ID
(2) People and their year of birth
The relationship is as follows:
Person 1 -----> 2000
Person 2 -----> 2001
Person 3 -----> 2002
Person 4 -----> 2001
---------
----
Person n -----> 2005
The above is not a function because there is a possibility that a more than one person will have the same year of birth.
