| Abstract: | A single determining approach judging whether an extreme value for a single variable function of first degree exist or not is given in this paper. On the other hand, we can also determine the extreme value from the quantities of stable points that we have got, and at the same time it is necessary to give the maximum and minimum of an extreme value. |

| Keywords: | extreme value determining approach single variable function of first degree |
