(10 points) A continuous function f, defined for all I, has the following properties: 1. f is decreasing 2. f Is concave up 3. f (16) = -3 4. f' (16) = - Sketch a possible graph for f, and use it to answer the following questions about f. A. For each of the following intervals, what is the minimum and maximum number of zeros f could have in the interval? (Note that if there must be exactly N zeros in an interval, the minimum and maximum are both N.) minimum maximum -OO
