To determine

(a)

The sets $\left\{\left({}^{-}1,2\right),\left(0,0\right),\left(1{,}^{-}2\right)\left(2^{\frac{1}{2}}{,}^{-}{2}^{\frac{2}{3}}\right)\right\}$ of ordered pairs are functionsthat give a rule.

To determine

(b)

The sets $\left\{\left(-6,0\right),\left(0,6\right),\left(5,11\right),\left(\sqrt{3},\sqrt{3}+6\right)\right\}$ of ordered pairs are functionsthat give a rule.

To determine

(c)

The sets $\left\{\left(-1,1\right),\left(1,1\right),\left(2,4\right),\left(\sqrt{3},3\right)\right\}$ of ordered pairs are functionsthat give a rule.
