Es stimmt, dass Sie die Figur mit anderer Software zeichnen können, und das hat sicherlich einige Vorteile. Sie können sie aber auch mit LaTeX zeichnen, und dann müssen Sie sich keine Gedanken darüber machen, Gleichungen hinzuzufügen.Hierist eine ausführliche Diskussion dieses Themas.
\documentclass[tikz,border=3.14mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.16}
\begin{document}
\begin{tikzpicture}[declare function={%
f(\x)=pow((x^7+3*x^6-2*x^5-x^4-3*x^2+1)/(x^4-2*x^2),1/3);}]
\begin{axis}[xmin=0,xmax=5,ymin=-0.5,ymax=6,xlabel={$x$},ylabel={$y$},grid=major,
title={$\displaystyle f(x)=\sqrt[3]{\frac{x^7+3x^6-2x^5-x^4-3x^2+1}{x^4-2x^2}}$}]
\addplot[color=blue,semithick,domain={sqrt(2.035)}:5,samples=71] {f(x)}
node[pos=0.75,above,sloped]{$y=f(x)$};
\addplot[color=blue,semithick,domain=0.55:1.11,samples=71] {f(x)};
\addplot[color=green!70!black,domain=0:5,samples=2] {x}
node[midway,below,sloped]{$y=x$};
\addplot[color=green!70!black,domain=-0.5:6,samples=2] ({sqrt(2)},{x})
node[midway,above,sloped]{$x=\sqrt{2}$};
\addplot[color=red!70!black,domain=0:5,samples=2] {1.075};
\end{axis}
\end{tikzpicture}
