Consider the following graph of the second derivative, f"(c), for some function f(I): Identify each of the following statements as true or false: f (x) is concave up at c = -( True False f(x) is concave up at a = 2 Lh True False If f(x ) has a local extreme at & = 4, then it must be a local X minimum. True False In If f(e ) has a local extreme at c = -5, then it must be a local minimum. True False
