Below is the graph of \( f^{\prime \prime}(x) \) which is the second derivative of the function \( f(x) \). Where, approximately, does the function \( f(x) \) have points of inflection? \[ \begin{array}{l} x=0 \text { and } x=2.5 \\ x=-1, x=2 \text { and } x=3 \\ x=-1.5 \text { and } x=4 \\ x=-1.5 \end{array} \]
