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
y=\[y=\sqrt{x-7}\]sqrt{x-7}\]
then the range is greater than or equal to 0 and the domain is x greater than or equal to 7

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 \[Y = \sqrt{X} -7\]
yeah parenthesis are important
