Answer 2

Any ideas?
:-)

Answer 3

2-4??

Answer 4

Correct!
How do you know?

Answer 5

because it is the only place where the line is the same (i have no idea how to make it sound smart)

Answer 6

The same what?

Answer 7

I honesty dont even know how to word it.. :(

Answer 8

Its the only part that doesn't change

Answer 9

Good, think about "what" is being constant in the interval 2-4?

Answer 10

What exactly is NOT changing as you move from 2 towards 4 on the x-axis?

Answer 11

the number of (x) hours?

Answer 12

since the hours keep going down except on 2-4 then it starts going down again, so 2-4 is the only time its staying consistent

Answer 13

Staying consistent at what value?

Answer 14

value?? I dont know :( im really bad at this...

Answer 15

Look at the y-values in the interval, what is it?

Answer 16

its decreasing?

Answer 17

Between 2-4?

Answer 18

no, it, uhm, *stays the same*

Answer 19

Thanks for the help, but i dont want to waste your time anymore

Answer 20

Yes.

What does it stay the same at?

What is the y-value at 2?
At 3? And at 4?

Answer 21

15?

Answer 22

YES!!!

Exactly

that is the "constant" value

Answer 23

oooooh ok!!! So basically "instead of decreasing at 2-4 it stays consistent at 15."

Answer 24

Not just "basically" but that is exactly how you figure these kind of questions out :-)

Answer 25

Look along the x-axis and see how the valued of the graph of the the function change.

Answer 26

have a nice day
