Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.

v=lwh
v=4x2x2
Answer:
C and D have the same volume
Step-by-step explanation:
For figures such as B, C, and D, with the top area is the same as the bottom area, the volume is the product of the base area and the height. The base area of all these figures is the same, so those (among B, C, and D) with the same height have the same volume.
C and D both have a base area of 20 cm^2 and a height of 5 cm, so both have the same volume.
___
For figures such as A and E, with a top area of zero, the volume is 1/3 the product of base area and height. If the heights of A and E were the same, they would have the same volume. The heights are different, so they don't.
None of the figures with non-zero top area have 1/3 the height of either A or E, so none are equal in volume to either of these.
-0.3125 is the answer, but you probably have to round
Y + 6 2/3 = -14 1/2
-6 2/3 -6 2/3
——————————
Y = -21 1/6
