Answer :
The domain of the function y = √(x + 6) - 7 is x > -6
How to determine the domain of the function?
The equation of the function is given as
y = √(x + 6) - 7
Set the radical greater than 0
x + 6 > 0
Subtract 6 from both sides of the equation
x > -6
Hence, the domain of the function y = √(x + 6) - 7 is x > -6
