MATH 133 -- Problem Set 4 grading instructions:

Section 1.8/1,16,19,21,28,48;
Section 2.1/4,6,14,18;
Section 2.2/1,2,8,9,12,15,29.

1.8/1  -- 4 points (1 each part)
 
    16 -- 10 points: part a 4, part b 2, part c 2 (graph should show 
          "hole" at a = 3; take off a point if it doesn't), part d 2 
      
    19 -- 6 points (2 for each limit, 2 for sketch) 
    
    21 -- same as 19
    
    28 -- 4 points. Idea is to do something like 16 a above.
          For full credit they should give at least 4 values with 
          h getting small (.001 or so)  
    
    48 -- 8 points.
                   
2.1/4  -- a 6 points, b 2 

    6  -- 4 points (one for each question asked)
    
    14 -- 6 points (-1 for each one out of order)
    
    18 -- 4 points (1 for squaring (2+h), 1 for simplifying top, 1 for
                    canceling h's, 1 for value)
    
2.2/1  -- 2 points (idea is to compute difference quotients from table,
                    taking h = -.002, -.001, .001, .002)

    2  -- a: 5 points, b: 2 points, c: 2 points
    
    8  -- 5 points (one for each of a,b,c,d,e)
    
    9  -- 5 points (there are many correct answers here -- check 
                    carefully!)
    
    12 -- 6 points (2 for coordinates of each point)
    
    15 -- 4 points (1 each part)
    
    29 -- 4 points
   
Total = 95 points
