What is the inflection point of the curve y = x ^ (1 / 3)? If y is derived twice as a function with X as the denominator, how can we find its inflection point if y '' = 0 and the molecule is a constant

At the inflection point, the second derivative is equal to 0, and the sign of the first derivative remains unchanged on both sides of the inflection point
