Your notation is not clear, but an inflection point is a point at which the curvature changes sign, in practice this means that it is a local extrema of y'.Quote:

As Captain Black said, an inflection point occurs at a local extremum of y' which, in turn, mean that y"= 0 (since y" always exists for this function).
Take the second derivative of this function, set it equal to 0 and use Newton's method to solve the equation.
