To write the Cartesian equation for the given parametric equations ( x = t - 2 ) and ( y = -(t^2) + t + 1 ), eliminate the parameter ( t ) by isolating ( t ) in one of the equations and then substituting it into the other equation.

From the first equation: [ x = t - 2 ] [ t = x + 2 ]

Substitute ( t = x + 2 ) into the second equation: [ y = -(x + 2)^2 + (x + 2) + 1 ]

Now expand and simplify to obtain the Cartesian equation.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
