What do you think the function would be

heatherlester · Answer

C=11n

anthonyym · Answer

Yes that's right

heatherlester · Answer

Is it continuous or discrete that's the problem I am having

anthonyym · Answer

http://mathbitsnotebook.com/Algebra1/FunctionGraphs/FNGContinuousDiscrete.html Basically a continuous function has connected lines, while discrete is like a scatter plot

heatherlester · Answer

So that would be continuous right

anthonyym · Answer

Yes

Thanks!😄

anthonyym · Answer

Oops I meant that a graph is continuous if all the points are connected, meaning there are no asymptotes.
For example, if you graph y=1/x, it is not continuous because the graph separates at the x-axis

Still makes sense but more sense now thank you
