Graph the pair of parametric equations by hand, using values of t in [-2,2]. Make a table of t-, x-, and y-values, using t = -2, -1, 0, 1, and 2. Then plot the points and join them with a line or smooth curve for all values of t in [-2,2]. Do not use a calculator.x = -t2 + 3, y = t - 3
What will be an ideal response?
