Choose the graph of a function $f$ that satisfies $$\begin{array}{c}{f}^{\prime }(0)\text{ does not exist};\\ f^{″}(x)>0\text{ if }x<0;\\ f^{″}(x)>0\text{ if }x>1;\\ f^{″}(x)<0\text{ if }0<x<1\end{array}$$ ($f^{\prime }$ is the derivative of a function $f$, $f^{″}$ is the second derivative of a function $f$).
