## Description

Given a function $f\left(x\right)$ and a range $R$, it constructs a curve described by $f\left(x\right)$, where $x\in R$.  Given a function $f\left(x\right)$ and two reals $a$ and $b$, it constructs a curve described by $f\left(x\right)$, where $x\in \left(a,b\right)$.  Given an expression $f\left(x\right)$, an identifier $x$ and a range $R$, it constructs a curve described by $f\left(x\right)$, where $x\in R$.  Given a list $\left\{{f}_{1}\left(x\right),{f}_{2}\left(x\right)\right\}$, an identifier $x$ and a range $R$, it constructs a curve described by $\left\{{f}_{1}\left(x\right),{f}_{2}\left(x\right)\right\}$, where $x\in R$.  Given a list $\left\{{f}_{1}\left(x\right),{f}_{2}\left(x\right)\right\}$ and a range $R$, it constructs a curve described by $\left\{{f}_{1}\left(x\right),{f}_{2}\left(x\right)\right\}$, where $x\in R$.
