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.
69 - 3a = 0
69 - 3a (-69) = 0 (-69)
-3a = -69
-3a(/-3) = -69(/-3)
a = 23

Answer:
0.5
Step-by-step explanation:
The given ordered pairs are: (1,2) (2,2.5) (3,3) (4,3.5) (5,4)
The corresponding sequence is :
2,2.5,3,3.5, 4,....
We can see that there is a common difference of d=0.5.
Better still we could use the slope formula:
![m = \frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20)
We substitute the point (1,2) and (2,2.5).
The rate of change of this sequence is:
![m = \frac{2.5 - 2}{2 - 1} = \frac{0.5}{1} = 0.5](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B2.5%20-%202%7D%7B2%20-%201%7D%20%20%3D%20%20%5Cfrac%7B0.5%7D%7B1%7D%20%20%3D%200.5)
