Extreme Value Theorem

Homework #8

1.   #14, page 712   

You will be using the Extreme Value Theorem to find the answers.   

Note:  for those of you with graphing calculators, you can graph the function and look to “see” where absolute maximum and minimum values occur on the interval [-1,2].  However, you will receive no credit if you just use the graph to answer the question!!  You have to use calculus to find the answer, or no credit !!!

2.   #26, page 713       I expect to see as all details

3.   #38, page 713     

You must show Step 1 through Step 5 (page 706)  in your solution to this word problem.  A diagram is essential for figuring out the formula for the function representing total cost, which is what you are asked to minimize.

4.   #32, page 722  

Use implicit differentiation to find the slope at the given point.  With the slope value and the point (1, 2), you can find the equation of the tangent line.
