Given the function f(x) = 3x^4 - 8x^3 + 12x^2 - 5, identify all critical points and classify them using both derivative tests.
💡 Hint: Apply both tests for a comprehensive analysis.
A cylinder's volume is represented by V(r) = πr^2h. If the height is constant at 10 cm, find the radius that maximizes the volume.
💡 Hint: Focus on the volume expression to simplify the terms!
