ok i tried to plot $y^3−3y^2−x−x^3+2=0, |x|<1$ but could not do so
spent about an hour trying to find a useable example but didn't
i am new to tikz but this is not a function...
here is the code I tried. just borrowed a previos on i thot I could just replace the expression but no
\begin{tikzpicture}
%preamble \usepackage{pgfplots}
\begin{axis}[xmin=-1.8, xmax=1.8, ymin=-3, ymax=3, axis lines=middle, ticks=none]
\addplot[
draw=red, smooth, ultra thick, dashed,
domain=-1.5:1.5,
smooth
]{-x-x^3+2}
%{y^3−3y^2−x−x^3+2=0}
\foreach \x in {-1,0,1} { (axis cs:{\x},0) node[below right] {\x} };
\end{axis}
\end{tikzpicture}
