Parametric Functions Practice Test

$$C_1$$ and $$C_2$$ trace different curves because the equations are different functions of the parameter.

$$C_1$$ and $$C_2$$ trace the same curve, but $$C_2$$ is traversed more quickly than $$C_1$$ for $$|s|>1$$.

$$C_1$$ and $$C_2$$ trace the same curve, but $$C_2$$ is traversed in the opposite direction of $$C_1$$.

$$C_1$$ and $$C_2$$ trace the same curve, but $$C_2$$ only traces the portion of the curve where $$x \ge 0$$.
