Below is the graph of
the derivative of a function
defined on the interval (0,8). You can click on the graph to see a larger
version in a separate window.
Refer to the graph to answer each of the following questions. For part
(A), use interval notation to report your answer. (If needed, you
use U for the union symbol.)
(A) For what values of in (0,8) is concave down? (If the
function is not concave down anywhere, enter "{}" without the quotation marks.)
Answer:
(B) Find all values of in (0,8) is where has an inflection point,
and list them (separated by commas) in the box below. (If
there are no inflection points, enter -1000.)
