Cartesian Equation Graph HEELP!!

1. x=t, y=square root of t, t>0
cartesian equation: y=root of x

2. what portion of the graph of the cartesian equation is traced by the parametrized curve?

3. I don't understand how to find the solution

When t=0, what are x and y? If t> 0, what are x and y? If t< 0, what are x and y? What part of the graph of $y= \sqrt{x}$ do you lose by dropping the t< 0 part? What part is left (the t> 0 part) ?

Does the problem itself mention the Cartesian equation $y= \sqrt{x}$? It would be a better problem if it asked "What portion of the graph of y= x2 is traced by the paramtrized curve?"
