hi guys i have some exercises about findinfg domain that i cannot do
z=square root of y-2x+x^2
z=(square root of 2x-y+2 )-(square root of x+y+1)
thanks in advance
Where the square root of a real number exists as a real number?
The intersection of the corresponding domains.´
z=(square root of 2x-y+2 )-(square root of x+y+1)
