Work Problem 1 ( , Consider the function f(a:) = :64 + 22:3. (a) Find the x- and y-intercepts of the graph of f (if an?)- (b) Find the intervals on which f is increasing or decreasing and the local extreme values (:13- and y-coordinates) of f . (c) Find the intervals of concavity and inection points of f. (d) Sketch the graph of f. Work Problem 2 ( (a) Sketch a graph of a function f such that: 0 f' > Oandf\" Oandf\" > 0.fora: > 3. (b) Does the graph of the function f in Part (a) have an inection point? Explain
