Answer 2

Domain: all x-values
Range: All y-values

Answer 3

you have the graph, everything is basically given, you can see graphically the domain, range and the y-intercept

Answer 4

oh right.

Answer 5

Got it now?

Answer 6

Yeah, except for the part where it says y-intercept. I forgot what that was.

Answer 7

Where the function crosses the y-axis

Answer 8

Got it now?

Answer 9

I think so.

Answer 10

hmm, did you get 3?

Answer 11

For which one?

Answer 12

Domain, Range, or Y-intercept?

Answer 13

y-intercept

Answer 14

Yeah 3.

Answer 15

Okay, so the y-intercept is when the function crosses the y-axis
This line in red

Answer 16

Alright, that above was just showing what the y-axis was, sure you know that though.
So now was the function in the problem growth or decay?

Answer 17

Growth?

Answer 18

Correct, have a good day

Answer 19

Thanks homie.

Answer 20

???

Answer 21

The range isn't just 1 number. nor is the domain
It is all the x-values/y-values it is defined for.
Basically, you are saying that The function is only defined at (9,10) which is one point

Answer 22

Oh ok.....

Answer 23

So, is it like all these numbers?

Because I'm still confused...

Answer 24

Hi there!

You want to find the domain and range right?

To do that, the domain is all the x-values and range is all y-values
So basically if you have a function like this:
https://www.desmos.com/calculator/uearfprjvi
The domain is from \[(-\infty, \infty)\] because for that function all x-values are defined.
But the range is not \[(-\infty, \infty)\] because we don't see y-values going below 0

Answer 25

As of what I see on your graph, my function is similar because it uses a simple exponential function, so what do you think the range is?

Answer 26

Yes, that is a great explanation Ashoka!
Welcome to QC also
And now do you get it Supie?

Answer 27

for the 10 and 3? I'm not sure tho I'm still confused.

Answer 28

for the range*(

Answer 29

range is from 0 to infinity because that's where the function goes, from 0 to infinity, never does y=-1 or anything like that

Answer 30

Yeah that is correct Darkknight, wow nice explanation, and ty for welcoming me
Supie are you all good now or...

Answer 31

Oh ok so I'm wrong then?

Answer 32

I have no clue what u mean by the 10 and 3

Answer 33

same I'm jus confused.

Answer 34

You see the arrow, it points on so the function continues forever, for ex:

the domain isn't from -7 to -3, its a line so it extends forever

Answer 35

So the range is the function?

Answer 36

The range is from 0 to infinity

Answer 37

So thats what I put in there? 🤔😕🤷‍♂️

Answer 38

yep

Answer 39

Yes. that is what u put there
