[declare function = {radius(\phi)=sqrt((3*sin(\phi)+cos(\phi)) / (sin(\phi)^3 -cos(\phi)^3)); },]

\draw[->] (-3,0) -- (3.4,0);

\draw[->] (0,-2) -- (0,4.2);

\draw[domain=50:{atan(-1/3)+179.99}, variable=\phi, red, smooth, ultra thick] plot ({radius(\phi) * cos(\phi)}, {1 + radius(\phi) * sin(\phi)});

\draw[domain=-130:{atan(-1/3)-0.01}, variable=\phi, red, smooth, ultra thick] plot ({radius(\phi) * cos(\phi)}, {1 + radius(\phi) * sin(\phi)});

\end{tikzpicture}

ok wanted of modify this graph to be this

$y=−\sqrt{\dfrac{(x2+1}{2}}\textit{ (c) }−\infty<x<\infty$
