1.52 rods
4⅙ fathoms
7.62 meters
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 formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
