Abstract
The cognitive, mathematical, and technological processes undertaken by senior secondary
students as they searched for a complete graph of a relatively difficult cubic function were
investigated. Particular circumstances: that became defining moments in the solution were
identified. Those related to students’ responses to particular views of the function are
presented. A variety of processes were used, however, a mental image of possible forms of
a complete graph, understanding the use of graphing calculator features such as Zoom Fit,
and the effect of each value in the WINDOW settings facilitated the students’ solutions.
