Question

@aditya96 help?? :)

Answer 1

in the first one the part inside the root should be positive
so we con write it as \[6x+42{\ge}0\]
=\[6x {\ge}-42\]
=\[x {\ge}-7\]
is the domain

Answer 2

@aditya96 <33 & the second?

Answer 3

in the second one domain can be found as in the first one but as we take values of x greater than or equal to zero 0 we substitute 0 in the equation to get -5
now if we take any value other than 0 then answer would be \[y {\ge}-5\]
