√x2-x-1=0
x2-x-1 greater than equal to 0
x2-x greater than equal to 1
x(x-1) greater tha equal to 1
therfore x>=1 and x-1>=1
x2-x-1 greater than equal to 0
x2-x greater than equal to 1
x(x-1) greater tha equal to 1
therfore x>=1 and x-1>=1

Dear student
We have,f(x)=1x2−x−6√Clearly,x2−x−6>0(x−3)(x+2)>0(x>3 or x<−2)x∈(−∞,−2)∪(3,∞)Hence, Domain(f)=(−∞,−2)∪(3,∞)
Regards
