Step-by-step explanation:
Inflection points are where a function changes concavity (the second derivative changes signs). At x = 4, f"(x) goes from negative to positive, so that's an inflection point. However, at x = 8, we don't know if f"(x) changes signs or not. So we can't say that that's an inflection point.
The answer is 18
2 to the 3rd power would be 2*2*2 which is 8
8 x 4=32
32/2=16
16+2=18

Im in the same boat. If you Uninstall and reinstall it you get more of the thingys to ask questions. (I learned that today)
