Find the intervals of concavity and inflection points of the function. (Give your intervals of concavity in interval notation. If an answer does not exist, enter DNE.) V(x) = x4 + 4x3 – 48x² + 6 concave up concave down inflection point (х, у) %3D (smaller x-value) inflection point (х, у) %3 (larger x-value)
