Determine the domain of this function
f(x)= square root (x + 6)/ x^2-4x+3
please explain how to do this and please put answer in interval form.
ok so i factor out the denominator (x-3)=0 (x-1)=0
What does the book say?
Edit 1: Just noticed that you said . In this case you need to find the places where .
On , and , so .
On , and , so .
On , and , so . (Note that this interval includes the two points where the denominator is zero.)
On , and , so .
So the domain is .
Edit 2: It's definitely not all real numbers. Either the book is wrong or you're reading the answer to the wrong problem.
