Find the domain of the function :`f(x)=(log)_((x-4))(x^2-11 x+24)` – InterviewSolution

1.	Find the domain of the function :`f(x)=(log)_((x-4))(x^2-11 x+24)`
Answer» Correct Answer - `(8,oo)` `f(x)=log_(x-4)(x^(2)-11x+24).` `f(x)` is defined if `x-4 gt 0 " and " ne 1 " and " x^(2)-11x+24 gt0` or `x gt 4 " and " ne 5 " and " (x-3)(x-8) gt 0` i.e., `x gt 4 " and " ne 5 " and " x lt 3 " or " x gt 8` or ` x gt 8` or domain`(y)=(8,oo)`
