Below is the graph of the derivative $f'(x)$ of a function defined on the interval (0,8). You can click on the graph to see a larger version in a separate window.



(A) For what values of $x$ in (0,8) is $f(x)$ increasing?

Answer:

Note: use interval notation to report your answer. Click on the link for details, but you can enter a single interval, a union of intervals, and if the function is never increasing, you can enter the empty set as $\lbrace\ \rbrace$.

(B) Find all values of $x$ in (0,8) is where $f(x)$ has a local minimum, and list them (separated by commas) in the box below. If there are no local minima, enter None.
