what is the domain of (square root of x) +7?

Answer 1

sqrt(x) + 7
Domain is the set of all possible values of x. Here, note that x is inside a squareroot radical sign and therefore cannot be less than zero.
Thus domain is all real numbers greater than or equal to zero. In symbols: [0 , +infinity)

Hope this helps :)
