Abstract

In learning mathematics, students often make mistakes or omissions in solving the questions given both the questions of practice, assignments, tests, and exams. This resarch purposes to determine the student^s errors mistakes in solving mathematical problems in the functions and inverse functions in SMA Negeri in Jakarta. The method used is qualitative research, This qualitative research includes case study research, with research subjects X MIPA students totaling 30 people who were selected based on purposive sampling technique where this subject is a subject who gets the material Functions and Inverse Functions. Data collection procedures are taken through the provision of test questions and interviews whit students. Data analysis includes data reduction, data presentation, and conclusions.
