A STUDY ON FUNCTIONS IN ENEM'S EVIDENCE

ENEM. Polynomial functions. Exponential and Logarithmic functions. Trigono-
metric functions.

The National High School Exam (ENEM) is the principal mean by which high school students
can get into public universities or private institutions. Moreover, the mathematics test is a deter-
mining factor in that regard, because it corresponds to 25% of the objective questions and, apart
from the dissertation, is the highest valued among the four major areas in the entire exam. De-
ficiencies in the education system increases the inequality in vacancy disputes. Because of this
reality, this work was elaborated in order to provide public school teachers a didactic material
and help in the understanding of Functions, Quadratic, Exponential and Logarithmic Functi-
ons, Trigonometric, Cycle and Triple Functions gonometric, which are part of the algebraic
knowledge content required for the exam. All those subjects correspond to 14% of the mathma-
tics questions approached between 2009 and 2019. The theoretical part of these concepts was
divided into five chapters, which present direct and contextualized examples, besides offering
commented questions from the exam at the end of each chapter.
