Using the second derivative number line below, determine the interval the graph, \( f(x) \), is concave up and down: (Note: Write your answers using interval notation.) a) The interval(s) over which the graph is concave down: b) The interval(s) over which the graph is concave up:
Expert Answer
If f??(x) is positive on an interval, the graph of y=f(x) is concave up on that interval. We can
