2. The function g is a continuous function. The graph below is the graph of y = g"(x). In part (a) and (6), answer the question and state what characteristic of the graph of y = g"(x) tells you the answer. (a) On what interval(s) is g concave up? (b) At what r-value(s) does g have an inflection point? (c) Use information from the graph of y = g"(x) to sketch a graph of y = g"(x) on the axes below. y =g"(x)
