Chapter 8.2, Problem 68PE

For Exercises 67-76, refer to the functions $y=f\left(x\right)$ and $y=g\left(x\right),$ defined as follows:

$\begin{array}{l}f=\left\{\left(-3,5\right),\left(-7,-3\right),\left(-\frac{3}{2\cdot }4\right)\left(1.2,5\right)\right\}\\ g=\left\{\left(0,6\right),\left(2,6\right),\left(6,0\right),\left(1,0\right)\right\}\end{array}$

Identify the range of $f.$
