Asked by Maggie

Find the domain of the function:
f(s)=sqrt s-1 over s-4
Answered by Damon
the numerator is sqrt(s-1)
you may not take the sqrt of a negative number so s must be >/= 1
the domain also must skip the point where the denominator is zero; that is when s = 4
Answered by Kayli
domain: all real numbers except 4
