Critical Point Quiz

Your quiz over critical points will cover:

1. Identify extrema on a graph (find extrema over different intervals...like #3 and 4 from the HW).  Remember, open intervals can NOT be considered extrema and constant functions are considered BOTH max and mins.
2. Finding critical points.  You should be able to find places that the derivative equals 0 and DNE.  Check your critical points to make sure that they are actually in the domain of the original function. If your derivative is too hard to set equal to zero and solve, graph the derivative and look at its zeros.
3. Given a a function, you should be able to use your calculator and locate extrema over given intervals.
