QUESTION 5

1. Consider the function f(x) = - x2 + 12x - 32.
   a) In the following blank, write the word maximum if the graph of f(x) has a maximum, the word minimum if the graph of f(x) has a minimum, or neither if the graph of f(x) does not have either. 
   
   b) If the graph of f(x) has a maximum or minimum, write the maximum/minumum value in the blank.  Else, write none.
   
   Note: for b, your answer should be a single number if you think there is a maximum/minimum.
