1. Graph the following function
2. [itex]\sqrt[3]{(x^{2}-1)^{2}}[/itex]
3. I got the first derivative to be [itex]\frac{4x}{3\sqrt[3]{x^{2}-1}}[/itex] but am having trouble with the second derivative to get the concavity. So far I have [itex]\frac{4*3\sqrt[3]{x^{2}-1}-4x*3*\frac{1}{3\sqrt[3]{x^{2}-1}}}{9\sqrt[3]{(x^{2}-1)^{2}}}[/itex]
