mojhsa [17]

Answer:

C. f has a relative maximum at x = 1.

Step-by-step explanation:

A. False.  f(x) is concave down when f"(x) is negative.  f"(x) is the tangent slope of the graph, f'(x).  So f(x) is concave down between x = -1.5 and x = 1.5.

B. False.  f(x) is decreasing when f'(x) is negative.  So f(x) is decreasing in the intervals x < -3 and 1 < x < 2.

C. True.  f(x) has a relative maximum where f'(x) = 0 and changes from + to -.

Lin took 75 boxes of carrots and 80 boxes of potatoes to the market. She sold 68 boxes of carrots and 71 boxes of potatoes. How
enot [183]

For this case we have:

x: Represents the number of carrot boxes

y: Represents the number of boxes of potatoes

Initially we have:

x = 75\\y = 80

If you sold 68 boxes of carrot we have:

x = 75-68 = 7

If you sold 71 boxes of potatoes, we have:

y = 80-71 = 9

The number of boxes I take home is given by:x + y = 7 + 9 = 16

ANswer:

7 boxes of carrots left

There are 9 boxes of potatoes left

A total of 16 boxes remain
