Question 117245: I'm not exactly sure what section this is either. I'm realy sorry! But, if you don't mind, can you please help me with this one too?
f(x)= {-1 for 0< or equal to x<1
{-3 for 1< or equal to x<2
{-5 for 2< or equal to x<3 and so on...Graph f(x) for 0
Answer by Edwin McCravy(20056) About Me  (Show Source):
You can put this solution on YOUR website!

f(x)= {-1 for 0 < x < 1
      {-3 for 1 < x < 2
      {-5 for 2 < x < 3 and so on...Graph f(x) for 0

This is a step function. The " [ " means the point IS included.
Your book or teacher may put a darkened circle there. The " ) " 
means the point is not included.  Your book or teacher may put
a open circle there.

The left end of each "step" below is included in the graph and 
the right end is not included.  The "steps" keep going down to
the right and never stop.
