The function f is continuous on [0,3] and satisfies the table below.

a.) Find any absolute extrema of f and where they occur.

b.) Find any points of inflection.

c.) Sketch a possible graph of f.

I have a test tomorrow and supposedly this problem is related to one on the test, so I would like to get it right, but the table just confuses me. I hope its not a simple solution, I'll feel stupid.
