Consider the function f(x) = 4(x - 2)3/3. For this function there are two important intervals: (-0o, A) and (A, co) where A is a critical value. Find A For each of the following intervals, tell whether f(x) is increasing (type in INC) or decreasing (type in DEC). (-00, A): (A, Do): For each of the following intervals, tell whether f(r) is concave up (type in CU) or concave down (type in CD). (-00, A): (A, Do): Submit
