What is the domain of the function y = √x + 4 ? also: what is the domain of the function y= √x + 6 - 7 two separate equations

Hello from MrBillDoesMath!

Domain:  x >=0 for both cases

Discussion:

Assuming we are dealing with real valued functions, the domain of

y = x^(1/2) +4

is the set of all "x" such that x>= 0  (so we are taking the square root of a positive, or zero, real number)

The domain of  x^(1/2) +6 -7 is the same as for the last function  and for the same reason.

Thank you,

MrB

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?
