Abstract
Students do not necessarily use the definitions presented to them when determining examples or non-examples of given mathematical ideas. Instead they utilize the concept image they carry with them as a result of experiences with such examples and non-examples. Hence teachers should try exploring students images of various mathematical concepts in order to improve communication between students and teachers. This suggestion can be addressed through error analysis. This study therefore is a descriptive-qualitative type that looked into the errors committed by senior high school students in dealing with mathematical functions explored the underlying reasons for such errors and provided recommendations on how students could learn to manage their errors and how teachers could realize how to manage students errors. Initial findings showed that the students generally demonstrated mathematical logical and strategic errors. Mathematical error was generally exhibited in their inability to use properties and operations properly. Logical error was exhibited in their false arguments rearranging concepts improper classifications arguing cyclically and using equivalent transforms. Strategic error was manifested in their not being able to distinguish patterns lack of integral concept and not being able to transform a word problem into symbols. Errors prevailed despite the students positive view and confidence in mathematics not only because of poor image concepts but because of lack of exposure to certain important mathematical tasks. Further investigation on the other sources of these errors is therefore necessary.
