16. Parametric Equations

Graph the plane curve formed by the parametric equations and indicate its orientation.

$x\(\left\)(t\(\right\))=-t+1$; $y\(\left\)(t\(\right\))=t^2$

$-2\(\le\) t\(\le\)2$

Graph the plane curve formed by the parametric equations and indicate its orientation.

$x(t)=2t-1$; $y(t)=2\(\sqrt{t}\)$

$t≥0$
