Carlos and Ana were asked to find an explicit formula for the sequence -10,-4,2,8,...−10,−4,2,8,...Minus, 10, comma, minus, 4, c
mars1129 [50]

Answer:

Ana is correct

Step-by-step explanation:

Given

Sequence:\ -10, -4, 2,8

Carlos; f(n) = -10 + 6n

Ana; f(n) = -10 + 6(n-1)

Required

Determine who is right?

To do this, we simply test each sequence.

For Carlos:

When n = 1

f(1) = -10 + 6 * 1 = -10 + 6 = -4

When n = 2

f(2) = -10 + 6 * 2 = -10 + 12 = 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

f(1) = -10 + 6(1-1) = -10 + 6*0 = -10 + 0 = -10

When n = 2

f(2) = -10 + 6(2-1) = -10 + 6*1 = -10 + 6 = -4

When n=3

f(3) = -10 + 6(3-1) = -10 + 6*2 = -10 + 12 = 2

When n = 4

f(4) = -10 + 6(4-1) = -10 + 6*3 = -10 + 18 = 8

This is correct.

<em>Hence, Ana is correct</em>

Think of a situation in the real world where a relationship occurs between two sets. For example, I could list several different
Alla [95]

Answer:

See Explanation

Step-by-step explanation:

Required

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.
