Suppose that P2(I) = a + br + cris the second degree Taylor polynomial for the function f about a = 0. What can you say about the signs of a, b, f has the graph given below? (For each, enter + if the term is positive, and - if it is negative. Note that because this is essentially multiple choice problem it will not show which parts of your answer are correct or incorrect.) a is b is c is Note: You can earn partial credit on this
