Determine the intervals on which the following function is continuous. F(x)= x2-6x+5 / x2-1 on which interval is f continuous?

Question

anonymous · Answer

pretty much every function you know, unless it is written as a piecewise function, is continuous on its doman
so you are really being asked "find the domain of $f(x)=\frac{x^2-6x+5}{x^2-1}$"

anonymous · Answer

that is straightforward i hope
since it is rational the only numbers that are not included in the domain are the ones that make the denominator equal to zero

anonymous · Answer

i know that you have to factor right and which gives me x-5/ x+1

anonymous · Answer

oh no
set the denominator equal to zero and solve for $x$

anonymous · Answer

Okay.. Thanks I got the answer.. I made a mistake.
