完全に中央に配置されています。表示される唯一の理由は、2 つの空白行です。\\コードの関連部分 (行 82 ～ 91) の不要な部分をコメント アウトしました。

さらに、環境をグラフtikzpicture`tikzpicture でラップします(行 58 ～ 64):\raisebox-0.5\height{…}, you can centre thetext. Example for the first
\raisebox{-0.5\height}{\begin{tikzpicture}
\begin{axis}[
xmin=-1.3,xmax=1.3,ymin=-0.5,ymax=1.5
]
\addplot[thick,samples=20,domain=-1:1] {x^2};
\end{axis}
\end{tikzpicture}} &
