The maximum and minimum points occur when dy/dx=0. So you can look at the first graph and tell that there are 3 points of interest. At the first point, x=1

The maximum and minimum points occur when dy/dx=0. So you can look at the first graph and tell that there are 3 points of interest. At the first point, x=1 and d2y/dx2 is positive (so it is a minimum point) and the coordinates are (1,-2) as given in the question
