Which of the following graphs has f′(x)>0f^{\(\prime\)}\(\left\)(x\(\right\))\(\gt{0}\) at (−3,0)\(\left\)(-3,0\(\right\)) and (3,∞)\(\left\)(3,\(\infty\]\right\)), and f′(x)<0f^{\(\prime\)}\(\left\)(x\(\right\))\(\lt{0}\) at (−∞,−3)\(\left\)(-\(\infty\),-3\(\right\)) and (0,3)\(\left\)(0,3\(\right\))?
