Define the concavity of the function. The graph of the function is then $f(x) = x^4 - 4x^3 + 10$ . Find the intervals on which $f$ is increasing and on which $f$ is decreasing. Find where the graph of $f$ is concave up and where it is concave down. Find the local maximum or local minimum value of function if exist. [2+3+3+2]

Function: $f(x) = x^4 - 4x^3 + 10$ --- A function $f$ is concave up on an interval if its graph lies above all its tangent lines on that interval (opens upward, shape $\cup$ ). Equivalently, $f''(x) 0$ . A function $f$ is concave down on an interval if its graph lies below all its tangent lines o...
