Answer all, please

1. The graph of the derivative, f , of a function, f, is shown to the right. a. On what intervals is f increasing or decreasing? b. At what values of a does f have a local maximum or minimum? c. On what intervals is f concave upward or downward? d. Estimate the locations of the inflection points of f. 2. Let f(a ) be a function that is continuous on the interval [-1, 3]. The function is twice differentiable on (-1, 3) except at a = 1. The function f( ) and its derivative have the properties indicated in the table below, where "DNE" indicates that the derivatives of f(x) do not exist at a = 1. -1
