THE DERIVATIVE FUNCTION IN MATHEMATICS EDUCATION IN HIGH SCHOOL

Abstract

Calculating the derivative of a function f gives an expression, it also is a function. The derivative function  and the function f are interrelated from an aspect of graphs and algebraic expressions. The article shows the incomplete relationship between the initial function and the derivative function present in the current curriculum and textbooks of Mathematics High School in Vietnam. This suggests new types of tasks that can appear in analytics teaching and are suitable for multiple-choice questions.
