Answer
This is the graph of the given parameter:
Work Step by Step
Using the given equations, $x = 1 - t^{2}$ and $y=2t - t^{2} $create a table of values in terms of x and y, using values of t within the given interval ($ -1 \leq t \leq 2 $). Then, plot the calculated points from the lowest t value to the highest t value. This will give the direction of the curve.
