This learning resource focuses on the investigation of the scaling factor in mathematical functions, specifically in the context of designing suspension bridge cables. Students are tasked with exploring how different values of the scaling factor 'a' influence the shape and steepness of the parent function, f(x) = x². The resource includes several tasks that require students to sketch various cable designs based on the modifications of 'a', such as creating models for scaling (a=2), reducing (a=0.5), and reflecting (a=-1). Each task encourages students to engage in discussions about the implications of these changes on the physical design of suspension bridge cables, examining how the parameters affect the visual representation of the function and shape of the cable.
