Question

Which of the following does not represent the set of positive integers from 1 to 10?

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

{1, 2, 3 … 8, 9, 10}

{1, 2, 3, 4 …}

{positive integers from 1 to 10}

Answer 1

well if u take a look at the third option, it continues on to infiniti so it doesnt represent the positive integers from 1 to 10

Answer 2

Ok so its the Third Option?

Answer 3

yes

Answer 4

Ok Um What about this one? I think the answer is option 2 but im not shure
Which of the following is a subset of the set
A: {integers divisible by 2 from 2 to 20}

{24, 26, 28}

{4, 6, 8, 10}

{integers divisible by 4 from 2 to 40}

{0, 2, 4, 6 …}

Answer 5

The answer is the first.

Answer 6

nope its the second

Answer 7

Shh!

Answer 8

hahahah

Answer 9

ok so option 2 is correct

Answer 10

ty :D

Answer 11

How abotu this one i think its option 3 If C = {integers divisible by 2 from 1 to 20} and D = {integers divisible by 6 from 1 to 25}, what is C ∩ D?

{2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24}

{6, 12, 18}

{6, 12, 18, 24}

{

Answer 12

yes option #3

Answer 13

Sweet :D i think im getting the hang of it but i just cheking :P

Answer 14

If A = {2, 4, 6, 8, 10} and B = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, what is A B?

{2, 4, 6, 8, 10}

{1, 2, 2, 3, 4, 4, 5, 6, 6, 7, 8, 8, 9, 10, 10}

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

{ }
Isent it the first option? :)

Answer 15

welll its \( A \cap B, or\ A \cup B \)

Answer 16

sooo what is it?

Answer 17

the first one

Answer 18

oh so its the intersection of A and B
Then in that case its the first option like u said

Answer 19

kk so then this one would be the second chice?
If A = {positive integers divisible by 2} and B = {integers}, what is A ∩ B?

{ }

{2, 4, 6, 8 …}

{2, 4, 6, 8, 10}

{1, 2, 3, 4, 5 …}

Answer 20

Correct

Answer 21

:D kk this one is confusing The domain of the following relation: R: {(−4, 8), (8, 10), (5, 4), (1, 6), (5, −9)} is

{8, 10, 4, 6, −9}

{−4, 1, 5, 8}

{−4, 8, 5, 1, 5}

No domain exists

Answer 22

ok domain usually refers to the x values
In this case each paired coordinate is (x,y)
so for example (-4,8) the -4 is the x coordinate which would be included in the domain
So basically the domain us all x- coordinates
so Which option wld it be?

Answer 23

So would it be No Domain?

Answer 24

Or option 3?

Answer 25

ok lets go thru each element in the set
(-4,8) the x -coordinate is the -4
(8,10) the x-coordinate is 8
(5,4) the x-coordinate is 5
(1,6) the x-coordinate is the 1
(5,-9) the x-coordinate is the 5
So the domain would be all the x-coordinates

Answer 26

ts option 2 btw

Answer 27

kk ty

Answer 28

do u understand this?
If f(x) = 2x2 + 2, find f(5).

102

52

22

−1.5

Answer 29

ur x shld be replaced with 5 and then evaluate

Answer 30

What dose Evaluate mean again? XD

Answer 31

\( 2(5)^2+2 \)
so just solve

Answer 32

52?

Answer 33

oh thanks !! :P i have 2 more of these
Given the function g(x) = −4x + 5, find g(−4).

−11
