dtermine the domain and range of the following relation. y=square x-7

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

yeah parenthesis are important
