Student Guide gamut-eyed} FRQ 1 A graphing calculator may NOT be used for the following problem. The gure above shows the graph of f ', the derivative of a Micedifferentiable function f, on the interval [3, 4]. Answer the following questions based on the graph of f '. a) Find all xcoordinates at which f has critical values and identify them as a relative minimum, relative maximum, or neither. Justify your answer. b) On what open intervals contained in [3, 4] is the graph of f both concave up and decreasing? Justify your answer. c) Find the x~coordinates of all points of inflection on the graph of f
