Probably but then again maybe they want the set of all circles that pass through those points or maybe they want something else.  

I really like the question too.  You were asking us to help you understand.  

We really like such questions.  

Thank you  fortun and welcome to Web2 forum.     

Nice answer Chris  

Well I think the speed would be the dependant variable.

That is it would depend on the height of the roller coaster.

So I would put height on the horizontal axis and speed on the vertical axis.

so the domain would be height    [20,205]   in feet

and the range would be speed     [0,75]      in miles/hour

If you do not ask then you will not get help.

If you do ask then you may get help.

You decide  

I think you got a bit muddled there Tetration.  

$$\\FV=10000(1+0.07)^5\\
FV=10000(1.07)^5\\$$

$${\mathtt{10\,000}}{\mathtt{\,\times\,}}{{\mathtt{1.07}}}^{{\mathtt{5}}} = {\mathtt{14\,025.517\: \!307}}$$

$14,025.51

what equation?  You have just got two points there.   

Yea we sux.     

Did your rudeness help you get your question answered?      

$$5.3\times 10^{-3}$$

would be entered as 

5.3*10^(-3)

4 hours =4*60=240 minutes

so it will be

240/3
