For this question, why does the answer not include a plus or minus symbol? Why is it just the positive value

Something in a root can never be negative, so the parametric equation for y can never be negative

You only have to include +/- when you’re rooting something that wasn’t already rooted if that makes sense
Ahhh I get what you mean, thanks!
