Range is greater then or equal to -7
Domain is all real numbers

do you mean y=sqrt(x-7) (square root)

Oh I didn't think of that
Kizzy, can you rewrite the question using the equation mode

Answer 4

y=\[y=\sqrt{x-7}\]sqrt{x-7}\]

Answer 5

then the range is greater than or equal to 0 and the domain is x greater than or equal to 7

Answer 6

square root is positive, and the inside of the square root need to be positive if we're dealing with real numbers

Yes that is right
Originally I thought you meant
\[Y = \sqrt{X} -7\]
