Help please? Question attached below!

Answer 1

Oh, and d got cut off!

Answer 2

D is the right one
since the roots are differrent the domains change as wel!!

for instance the cube root of X can be negative whereas it is not the case in square root of X
square root of negative integers would be imaginary :P

Answer 3

Is D all or are there more? It's alright to have several answers!
