Describing Students' Representation Ability: Focus on Functions and Its Inverses Topic

The topic of functions is one of the topics in mathematics that involves various representations completely such as verbal representation, visual representation, and symbolic representation. So, this research aims to describe students' mathematical representation abilities on the topic of functions and its inverses. This study is a quantitative descriptive research that involved 15 eleventh-grade students at one of high schools in Sungai Penuh, Jambi, were selected through total sampling techniques as research subjects. The researcher gave three mathematical representation ability test problems, each of which represented indicators of verbal representation, visual representation, and symbolic representation. Students' answers were analyzed descriptively. The results of the study showed that in general students' mathematical representation abilities were relatively low, most students had tried to solve the problems but were not give complete answer. Therefore, teachers are expected to use appropriate learning methods to help students improve their mathematical representation abilities.
