Question 453185
You CANNOT divide by zero. So the denominator {{{x-4}}} can't be equal to zero. So this means that {{{x-4<>0}}}. Solve for x to get {{{x<>4}}}



So x cannot be equal to 4.



So the domain is the set of all real numbers except x can't be equal to 4. Basically, you can plug in any number you want but 4.
