Question 527908: what is the domain of this rotational function 5X/X-7 ??
Answer by jim_thompson5910(35256) About Me  (Show Source):
You can put this solution on YOUR website!
You cannot divide by zero


So when x = 7, the denominator is 0 (since x-7 = 7-7 = 0)


This means we have to exclude x = 7 from the domain.


So the domain is the set of all real numbers except x cannot equal 7.
