1Welcome to TeX.SX! The short answer is that, yes, it is possible to do this but I have to warn you that questions of the form "Please draw this for me", which show no effort on the part of OP, often don't get answered. You will get more help if you post some code showing what you have tried and give a minimal working example. A quick search on TeX.SX for drawing functions (with tikz or pstricks) will give you an idea of where to start from.– user30471Nov 9, 2017 at 14:42

Thanks to Sebastian, an answer would be:
\begin{tikzpicture}
\begin{polaraxis}[grid=none, axis lines=none]
\addplot[mark=none,domain=0:360,samples=300] {0.1 + abs(cos(4*x/2))};
\end{polaraxis}
\node at (3.45, 3.45) {$\mathcal{O}$};
\node at (3.45, 5.45) {\small{\textbf{(0,2)}}};
\node at (3.45, 4.8) {\small{\textbf{(0,9)}}};
\node at (5.25, 3.65) {\small{(8, i)}};
\node at (5.25, 3) {\small{(8, 10i)}};
\node at (1.65, 3.65) {\small{(2i+7, i)}};
\node at (1.65, 3) {\small{(2i+7, 10i)}};
\node at (3.45, 2.1) {\small{(9i+7,i)}};
\node at (3.45, 1.45) {\small{(9i+7,10i)}};
\end{tikzpicture}
