Answer:

Step-by-step explanation:
We have to vertically stretch the function
by a factor of 2.
Then the function will become
.
Then it is reflected across the x-axis.
So, the new function will be
.
Now, if the function is shifted down 3 units then the final function will become
(Answer)
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.
