Question

-------   y= X +6                    A   all real             y = x2+6                    B all real except x=6             y = 1/x+6                    C all reals except x = -6             y= 2x +6             y=2/3x +6             y = 1/2x-12 State the Domain -------   y= X +6                    A   all real             y = x2+6                    B all real except x=6             y = 1/x+6                    C all reals except x = -6             y= 2x +6             y=2/3x +6             y = 1/2x-12 State the Domain

Explanation / Answer

y= x2+6 is the same as above y= 1/x +6 [i'm assuming this is 1/(x+6)] if that is the casethen all reals except x= -6 because x=-6 would make y #e60000,because you cannot divide by 0 y=2x+6 is the same as y= x+6 y=2/3x +6 is also all reals because x can equal anything and ywill be defined [i'm assuming you mean y=(2/3)x +6] y= 1/2x-12 [y=1/(2x-12) ?] if that is true then the domain isall reals except x=6 because you cannot divide by 0
