Given that \(g(x)=3x^2\quad\)and\(\quad h(x)=x-2,\quad\) evaluate:
\(gh(1)\)
\begin{align}g(1-2) & = g(-1)\\
& = 3(-1)^2\\
& = 3\end{align}
\(hg(3)\)
\begin{align}h(3(3)^2) & = h(27)\\
& = 27-2\\
& = 25\end{align}
\(gh(3)\)
\begin{align}g(3-2) & = g(1)\\
& = 3(1)^2\\
& = 3\end{align}
\(gg(-2)\)
\begin{align}g(3(-2)^2) & = g(12)\\
& = 3(12)^2\\
& = 432\end{align}
