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

    this is difficult to explain in words...

    do I always use 0,1,and 2 to enter into the equation?

    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.

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

    no worries, I just wanted to make sure I understood the function before starting an explanation

    my suggestion is this, first mark your intervals on the x-axis with the appropriate (,),[, or ] notation

    then sketch the graph of the function with the rule that pertains to the appropriate interval
