6. The graph of h' should have two locations indicating that h has a slope of zero, one for a negative x value and one for a positive x value.  These should be the two zeros for h'.  h' should be positive, then zero, then negative, then zero, then positive.  Two graphs describe this:  D and E.  D is eliminated because the slope is changing should not show any change in concavity.

9.  The total number of barrels of oil that passed through the pipeline is or the area bounded by the function, t=0, t=24, and the t axis.  This approximately 600+600+600+600+600 or 3000 barrels. Answer D

 Since f is a linear function, f ' (x) is a constant, and f "(x) is zero.

Answer A
   
12. 

Therefore the limit from the left does not equal the limit from the right, no limit exists at x=2.

Answer E
   
13.  f is not differentiable at x=0 because of the discontinuity or x=2 because of the vertical tangent line.  Answer B

The sign of f " changes sign only at x =1.

Answer C
   
17.  From the graph we know that f(1)=0, f '(1)>0, and f "(1) <0 so the correct order is f "(1) < f(1) < f '(1) Answer D

I.  each term is getting larger so the series diverges.

II.  This series converges.

III diverges since the series is harmonic

22.  Answer A
   
23.  f is defined and continuous on the closed interval [a,b].  f has a relative maximum at x=c for some point c in the interval.  We do not know if at (c,f(c)) is a differentiable or non-differentiable point.  So we do not know if I is true.  But if f '(c) exists it must be zero.  If f '(c) exists, then the f "(c) must be negative.  II and III are true. Answer E
   
24. Since the slopes at the various points appear to be the sum of the x and y values then .  Also notice when the x coordinate is one less than the y coordinate the slope is -1. 

 

For A to be true at x=0 the slopes would equal 1.  Not true

For B to be true when x<0 slopes would all be positive.  Not true.

For D to be true as x is constant and y increases, the slope decreases.  Not true.

E is not true since the slopes do not follow the natural logarithm or logarithmic curve.
