Final answer:
The magic wand tool, the lasso tool, and the rectangular marquee tool all have the common function of selecting areas of an image for editing. Despite their different approaches to how selections are made, their primary purpose is to create editable selections.
Step-by-step explanation:
The magic wand tool, the lasso tool, and the rectangular marquee tool all share a common function within graphic design and photo editing software, which is 2) selecting. These tools are used to create selections on an image, allowing you to isolate and work on specific parts of an image without affecting the rest. The magic wand tool selects areas based on color and tone, the lasso tool allows for free-form and polygonal selections, and the rectangular marquee tool lets users select rectangular areas. Despite offering different methods of achieving a selected area, their primary function is to create selections for various editing purposes.
Additionally, it's important to note that all these tools can typically feature settings for feathering, which softens the edges of selections to create a more blended transition between the selected and unselected areas. However, feathering is a setting within these tools, and selecting is the main function they all share in common. Although the tools have much uses and applications in the fields of digital artwork and photo editing, the act of selecting remains their key shared feature.
