Match the parametric curve to its description. Be careful: It is possible that the same description fits more than one parametric curve! (a) (t + 1,4t−2) (1) A portion of a parabola. (b) (t2,3t2) (2) A straight line traversed at constant speed. (c) (cost,2(cost)2 + cost) (3) A straight line traversed at variable speed.
(d) ((2t + 1)sint,(2t + 1)cost) (4) A circle. (e) (2t−1,5) (5) Doesn’t match any other description.
(d) ((2t + 1)sint,(2t + 1)cost) (4) A circle. (e) (2t−1,5) (5) Doesn’t match any other description.
