How to recognize discontinuity of slope in numerical data

I am dealing with a set of data that, when plotted, shows a breaking point as shown in circles. How can I identify these points in the data without needing to plot them every time? I tried looking for discontinuity in the sllope, but that did not help.

Take the second derivative --
d2y = gradient(x,gradient(x,y))
Look for the spot where the second derivative changes from negative to positive.
