Answer 3

what is this

Answer 4

relax nd w8

Answer 5

okz but help me about dt qustion

Answer 6

for ln x , we need x as positive
x^2 and y^2 are always positive
so, x and y can take any real value , hence domain is x,y \(\in R\)

Answer 7

typo, \(x,y \in R^2\)

range of f is same as range of ln
so, it'll also be x,y

Answer 8

***it'll be \(Range : c \in R\)

Answer 9

listen?

Answer 10

yes?

Answer 11
