well, the way to sketch a "piece-wise" defined function is to attack each "piece" separately

this is difficult to explain in words...

first lets get the function written in notation so we can see what we are dealing with...one second

There are four parts to this question. a) find the domain, b) locate any intercepts, c) graph each function and d) based on the graph find the range. I don't understand where to start on any of it.

I had the flu and missed one class and I don't understand

this is what I think the function is...\[f(x)=x+3\], if \[-2\leq x <1\], 5 if \[x=1\], \[-x+2\] if \[x>1\]

yes thank you

my suggestion is this, first mark your intervals on the x-axis with the appropriate (,),[, or ] notation
anonymous
  • anonymous
then sketch the graph of the function with the rule that pertains to the appropriate interval
