y= 1/x −7
Find the domain of this function
Answered by Steve
If you meant what you wrote, then the domain is all reals except x=0

If you meant y=1/(x-7) then the domain is all reals except x=7.

In other words, all reals except where the denominator is zero.

the denominator cannot equal zero. X can be all numbers, real and complex, but not seven
