The paper’s greatest pedagogical contribution lay in its treatment of Functions and Graphs. A notoriously challenging question on inverse functions required students to first restrict the domain of a complicated rational function, then find the inverse, and finally solve an inequality involving composite functions. The subtlety was not in the algebra, but in the set logic: students had to recognize that the solution set was contingent upon the pre-image and image of the function. Many high-achieving students faltered here, not because they could not compute, but because they struggled to visualize the transformation of sets. This question became a litmus test for true understanding, separating procedural proficiency from mathematical reasoning.
