6. The below shows a parametric curve x = x(t). y = y(t), astsb. (a) Match a graph to each of the parametric curves given, for same t values by i. (-x(t), -y(t)) iii. (x(t) + 1, y(t)) ii. (-x(t), y(t) ) iv. (x(t) + 1, y(t) +1) Be sure to explain how you determined each of your matches. A D B E F (b) Provide formulas for r(t) and y(t) that could possibly represent the parametric curve (x(t), y(t)). Explain how your formulas could possibly represent the parametric curve (x(t), y(t) )
