3. Let f(x) = 3x4-4x3. We want to find the intervals on which f(x) is concave up or concave down, and any inflection points.Follow the steps below. (a) Find all values of x for which f"(x)-0. Show your work carefully. (b) Fill in the sign analysis table for f"(ax), including the conclusions about whether f(x) is concave up or concave down on each interval. Sign analysis table for f"(x) Test valueValue of f"x)Conclusion (concave up or concave down) Interval (c) Determine all points of inflection.
