Can someone help me with a few questions please? I will fan and medal!

OpenStudy (sagewilson):

We need the questions in order to answer them.

OpenStudy (isuckatschool43):

1 sec

OpenStudy (isuckatschool43):

OpenStudy (isuckatschool43):

i got Range: 3 Domain: {-9, -4, -1, 2, 5, 10}

OpenStudy (isuckatschool43):

not too sure, this topic is kinda new

OpenStudy (sagewilson):

Domain is correct, the range is just the Y coordinates in order from smallest to largest.

OpenStudy (isuckatschool43):

like this? {-8, -6, 3, 7, 11, 12}

OpenStudy (sagewilson):

mhm

OpenStudy (isuckatschool43):

okay thank you. i have some more if you have time

OpenStudy (isuckatschool43):

OpenStudy (sagewilson):

Sure just give me a min.

OpenStudy (sagewilson):

first off, are there answer choices?

OpenStudy (isuckatschool43):

no

OpenStudy (isuckatschool43):

and i think it is from (2,15) to (4,15)

OpenStudy (sagewilson):

I'm thinking that as well.

OpenStudy (isuckatschool43):

sorry i dont know why that sent

OpenStudy (isuckatschool43):

i was saying that all these questions say explain how you know at the end

OpenStudy (sagewilson):

Well you can just say this "Since I know that a constant function is a function whose y-coordinate value is the same for every input/x-coordinate value, and the coordinates (2,15) and (4,15) fit that description, it was the only choice that makes sense."

OpenStudy (isuckatschool43):

yeah ill try something like that

OpenStudy (isuckatschool43):

OpenStudy (isuckatschool43):

the value of the function is (-2,-3)? did i do that right

OpenStudy (sagewilson):

Yes you did it right.

OpenStudy (isuckatschool43):

okay. should i say something like - I know this because every y-coordinate value is the same for every x-coordinate value so going down from x=-2 I ended at y=-3 on the graph? I don't know if that really makes sense @SageWilson

OpenStudy (sagewilson):

No, that is fine. Leave it how you put it, it sounds good.

OpenStudy (sagewilson):

Leave it how you put it, it sounds good.

OpenStudy (isuckatschool43):

okay thanks. i think that is it for now
