yep

but there's also another place
When does it start decreasing in the left?

Answer 7

infinity?

Answer 8

negative infinity

Answer 9

(-infinity,-1)
(0,infinity)

Answer 10

-
don't tag me next time then, idk then

Answer 11

lol

Answer 12

your meaner then az!

Answer 13

wat?

Answer 14

@Extrinix

Answer 17

oh my-

Answer 18

may i lend a hand?

Answer 19

yep please

Answer 20

alright, so on the graph where it shows that it is decreasing look at the arrows those can help, and how the graph is set up and shows the area of it. the y would be alwaysinfinity but the x isn't because you can see the angle of the line and how it stretches across the y axis but not the x axis

Answer 21

yep

Answer 22

your looking for the dots or the way it goes down or where it starts, because if there are x,y coordinates its a different story

Answer 23

yep

Answer 24

the intervals are on the x-axis right?

Answer 25

does the U in the answer you put the shape, and are you allowed to have one coordanite or does it have to be two of them.

Answer 26

one

Answer 27

im not sure i guess to coordinates

Answer 28

midnightsky?

Answer 29

oh. alright lets see here

Answer 30

as you can see the graph shows that the middle of the line is increasing and the sides of it are decreasing, and we are looking for the decreasing interval.

Answer 31

yep

Answer 32

alright

Answer 33

so hats next

Answer 34

To find when a function is decreasing, you must first take the derivative, then set it equal to 0, and then find between which zero values the function is negative.

Answer 35

Since the only value that is negative is when x=0, the interval is only decreasing on the interval that includes 0.

Answer 36

alright

Answer 37

we know it's mostly decreasing so to find the decreasing interval we read left to right of the graph and if it goes down from left to right its decreasing and the opposite way is increasing, do you know how to find an interval?

Answer 38

i dont

Answer 39

i ant to end this uickly please type uicker lol

Answer 40

oh- okay, yea im sorry :> im trying my best to help

Answer 41

hats next

Answer 42

so the first one is wrong the infinity is is on the y, because the x doesnt go past-4

Answer 43

actually the first one should be, (-infinity, -2) should be one

Answer 44

alright

Answer 45

positive infinity i meant, sorry

Answer 46

it should be like (-,+) and it goes to (+,-) because its decreasing.

Answer 47

and the other should be like (-2, -infinity) and (infinity, -2)

Answer 48

theres only to not three

Answer 49

i meant, the last two, and which one like do you need, your not being very helpful to me.

Answer 50

the uestion says hich ones i need i guess the ones that arent decreasing

Answer 51

alright, so the ones increasing, do you know the f(x) function for the graph?

Answer 52

i dont

Answer 53

so you want me to do everything? you gotta help a bit because i want to help you not do it for you :)

Answer 54

lol im sorry im not sure

Answer 55

it's alright, if i have to find the function of the graph it'll take a bit if you don't mind :)

Answer 56

alright
