Other answers:

change the equation to \[x=\sqrt{y-4}\] and solve for y
take -4 on the left side
But the -4 is in the rt
u get y^2+4 = x
replace x by y and y by x u will get the inverse
what he said
Still a bit confused with what you do with the -4
i have added +4 on both sides so that -4 gets cancel on the right hand side
So I get 4+x=sqrt y
|dw:1359614352269:dw|....follow this
after this cancel -4 and +4 on right hand side
