Show that the curve whose parametric coordinates are `x=t^(2)+t+l,y=t^(2)-t+1` represents a parabola.

The curve describe parametrically by x =t^(2) +t+1,y=t^(2) -t+1 represents

The curve described parametrically by x=t^(2)+t+1,y=t^(2)-t+1 represents :

The curve described parametrically by x=t^(2)+t+1,y=t^(2)-t+1 represents

Find the equation of curve whose parametric equations are x=2t-3,y=4t^(2)-1 is

The curve described parametrically by x = t^2 + t +1 , y = t^2 - t + 1 represents :

The Cartesian equation of the curve whose parametric equations are x=t^(2) +2t+3 and y=t+1 is a parabola (C) then the equation of the directrix of the curve 'C' is.(where t is a parameter)

The Cartesian equation of the curve whose parametric equations are x=t^(2)+2t+3 " and " y=t+1 " is a parabola "(C)" then the equation of the directrix of the curve 'C' is.(where t is a parameter)
