Thin Lens Equation - Hypothesis

[J-Wang]

Homework Statement

Hi, I am writing a lab report, and I have no idea how to come up with a fitting hypothesis for this lab

Purpose: To determine the relationship among the focal length, the image distance, and the object distance of a converging lens.

The first thing you should do is use your knowledge of converging lenses to try and predict a relationship. Could you not use some geometrical optics to try and predict what the relationship may be?
