## Homework Statement

these are the function

1) f(x)=A(x)/B(x)

2) f(x)=√(A(x))

3) f(x)=√(A(x))/(B(x))

4) f(x)=(A(x))/√(B(x))

5) f(x)=√(A(x))/√(B(x))

6) f(x)=√((A(x))/(B(x)))

## The Attempt at a Solution

the domain are they right

1) { x∈ R : B(x) ≠ 0 }

2) { x∈ R : A(x) ≥ 0 }

well the other I don't know how to makes them ,,, can you give me some infos ,, i don't want the domains because i want to make them to learn and don't forget them later ,,,

i don't know how to have the domains because in the lecture the doctor give a example on potato so i got confused
