Question

MEDAL

Melinda has shown that a function, f(x), increases by 4 for every unit in the domain. What does this prove?

The function f(x) is an arithmetic sequence.

The function f(x) is a geometric sequence.

The function f(x) is not a sequence.

This does not prove anything.

Answer 1

@Loser66

Answer 2

@e.mccormick I really not know. I am sorry.

Answer 3

because to me, this does not prove anything. but it sounds not good at all

Answer 4

its okay @Loser66, can you help me in one last one i'm pretty sure you' ll know this one

Answer 5

it is a arithmetic sequence because for example when x increases 1 to 2 y's values lets increase from 2 to 6

Answer 6

and then when x goes from 2 to 3 y goes from 6 to 10

Answer 7

if u draw the graph it has a consant slope

Answer 8

like this

Answer 9

so what would the answer be

Answer 10

@kagıtucak a function is not a sequence, they work on the same way but they are not the same.
A function has a graph is a curve or a line
A sequence has a graph is a set of dots

Answer 11

a sequence does not have a graph

Answer 12

By definition, we don't know on what way the sequence works, therefore, we consider the similar form in function to consider the way it works.

Answer 13

its aritmetiv ı am sure of it y' values increases like this 2 6 10 14 18........

Answer 14

so, you can't conclude that it's a sequence or a function, And it is totally wrong when you say the function is..... a sequence.

Answer 15

answer ? is .....

Answer 16

@realmadridCR7 I stated out my opinion above. It's up to you to take it or not. "this does not prove anything"

Answer 17

what was your opinion

Answer 18

it is the first one ı am sure of it

Answer 19

if u draw the you can see that it will increase linearly from - infinite to + infinte

Answer 20

It would depend on what units are in the domain. You don't know that, which is why I agree with Loser66. You simply do not have enough information to say it is limited to a sequence.

Answer 21

Match the sequence (term) with the correct type of sequence (definition).

Match Term Definition
128, 32, 8, 2, ... A) Geometric, common ratio is 0.25
1, 3, 9, 27, ... B) Arithmetic, common difference is 5
5, 10, 15, 20, ... C) Geometric, common ratio is 3
20, 17, 14, 11, ... D) Arithmetic, common difference is -3

Answer 22

@e.mccormick

Answer 23

Well, do you see either a common difference or ratio on those? Do you understand how to find those?
