Ccnsiderthe function r) : 4-"5(:i: 4). This function has two critical points A

Consider the function f(x) x4/5(x Find A and B Hint: Write the derivative in the form 4). This function has two critical points A < B For each of the following intervals, tell whether f(x) is increasing (type in INC) or decreasing (type in DEC). ( 00, A]: [B, 00) The critical point A is a local (type in MAX, MIN or NEITHER) and the critical point B is a local (type in MAX', MIN or NEITHER) There are two numbers C < D where either 0 or is undefined. Find C and D Finally for each of the following intervals, tell whether f(x) is concave up (type in CLJ) or concave down (type in CD). (-00, C) (D, 00)
