Chapter 10.6, Problem 1PE

If $f$ and $g$ are continuous functions of $t$ over an interval $l,$ then the set of points $\left(f\left(t\right),g\left(t\right)\right)$ is called a $\text{\_\_\_\_\_\_}$ curve. The equations $x=f\left(t\right)$ and $y=g\left(t\right)$ are called $\text{\_\_\_\_\_\_}$ equations and $t$ is called the $\text{\_\_\_\_\_\_}$ .
