1-2 = -1
If that's what u mean
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:
It is the 3rd one 9/5y+9.
Y/12+6=-72 Y/12=-78 Y=-6.5
Half way in between -23 & 23 would be 0 because if you start on both sides and carefully go towards the middle evenly you will get zero on a number line
