This question is from the parametric equations chapter of my calc book.
I am given x =[itex]\frac{1}{\sqrt{t+1}}[/itex]
and y = [itex]\frac{t}{t+1}[/itex], for (x> -1)
Solving the x(t) for t, we get [itex]\frac{1- x^{2}}{x^{2}}[/itex]
Eliminating the parameters by substitution, we get y = [itex]1 - x^{2}[/itex] for (x > 0)
My question is, what process is used to determine the change in domain?(Please see attached photo to see the exact content my question has stemmed from)
Regards
