just started this subject and don't really understand it... :(   Do I just list all Z in a) b) and c)?

amistre64 · Answer

something like that

amistre64 · Answer

Z is the domain from which you get the values of x for the defining functions

amistre64 · Answer

the example used:  x=-1,-2,0,1,2  and dotted the rest
