This document provides information and tasks related to investigating parabolic curves through the design of suspension bridges and industrial packaging. It outlines three approaches - arithmetic, procedural, and conceptual - for examining parabolas in real-life applications. Students are asked to draw bridge plans showing supports, cables, and hangers on a coordinate plane and calculate related values. For packaging, students define the three investigation approaches and derive generalized equations to calculate box dimensions and capacity based on a given variable.
