16. Parametric Equations

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

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

$-2\le t\le2$

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

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

$t≥0$
