is it all values except where x=3
OpenStudy (anonymous):
no
OpenStudy (anonymous):
consider also at -3 the function is discontinious
OpenStudy (anonymous):
we're looking at limits
they both approach the same point from both sides, thus its a valid limit

what about at -6 they are both approaching +infinty,but it cant all real numbers cos the domain is already given
OpenStudy (anonymous):
lim x->-6 would just be +inf
also a valid limit
domain is given but range isnt
OpenStudy (anonymous):
sorry about that
OpenStudy (anonymous):
i would say
3 to 4
because limit doesnt exist at 3
and there is not graph between 3 and 4 thus there cant be a limit, unless i misread the graph
OpenStudy (anonymous):
no i misread the graph, you are correct

so we have to say \[x \in[-9,4]\] but \[x \neq 3\]
OpenStudy (anonymous):
so it is when x≠3?
OpenStudy (anonymous):
you're being asked when they exists, so all real between -9 to 4 except for 3
