Answer 1

*** Please pay attention to what I am saying instead of just blurting out answers ***

Answer 2

anyway, ⌊x⌋ means we round down to the nearest integer

so if x = 0.5, what's ⌊x⌋ equal to?

Answer 3

0.5

Answer 4

try one more time

Answer 5

or 5

Answer 6

what's the highest integer that is less than 0.5?

Answer 7

0.9

Answer 8

0.9 is not an integer

Answer 9

one last time... integers are positive and negative <<<WHOLE NUMBERS >>>

Answer 10

1.0

Answer 11

1.0 is NOT less than 0.5

Answer 12

we are looking for the greatest integer that is LESS than 0.5

Answer 13

0.5<1

Answer 14

one last time

we want an integer that is LESS than 0.5

1 is GREATER than 0.5 so it is not the answer

Answer 15

Please slow down and think a little harder.

Answer 16

YES !!!!!!!!!!!!!!!!!!!!!!

Answer 17

1 I WAS SO DEBATING ON IT

Answer 18

it is NOT 1

Answer 19

1 is GREATER than 0.5

we want an integer that is LESS than 0.5

keep trying.

Answer 20

hint: here are examples of integers: -1,0,1

what's the greatest integer that is LESS than 0.5?

Answer 21

is it 0 ?

Answer 22

good, that's it!

Answer 23

now, if we take ⌊x⌋ + 3 where x = 0.5, we get 0 + 3 = 3

so which graph crosses the point (0.5,3)?

Answer 24

*** take your time before answering ***

Answer 25

I need to get going home, be back in like 15 mins

Answer 26

it's C

Answer 27

try one more time. make sure you are looking at the point (0.5,3) and examine each graph slowly and carefully.

Answer 28

sorry i was busy
