So (f-g)(x) = 3x2 + x, so when x = 2, the function is 14
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.
Answer:

Step-by-step explanation:
7^5 means that there are 5 7s eg 2^4 would be 2×2×2×2
Answer:
None of these answers are correct.
Step-by-step explanation:
Perpendicular lines have opposite and reciprocal slopes, which means that we take the slope and we flip it. After we've done that, we change the sign.
Since the original slope is -7, first we flip it and get -1/7. Now we change the sign and get 1/7. Therefore, the perpendicular slope of this line would be 1/7
