Is the following function increasing, decreasing, or neither?

Volume of a gas as a function of applied pressure (assuming temperature remains constant)

For the function $g\left(x\right)=\mid 3x-6\mid +2$, what is the largest interval on which $g\left(x\right)$ is increasing?

For the given function, is it even, odd, or neither?

$y=\frac{x^3+2}{x^2-1}$

Analyze and graph the function $y=\frac{x^3}{343}$. What symmetries does it exhibit, and during which intervals is it increasing or decreasing?
