Find two different sets of parametric equations for y = x² + 6.

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.

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

$t\ge 0$
