16. Use the second derivative to nd the intervals where the function is concave up and concave down. Use your work to find the coordinates of the inection point(s). for) = 3:4 4x3 + 5 concave up: concave down: inection pt(s): x+1 x the interval [1, 2] . If the Mean Value Theorem can be applied, nd all value(s) 17. Determine whether the Mean Value Theorem can be applied to f (x) = on of c in the interval such that f '(C) = % . If the Mean Value Theorem cannot be applied, state why
