What does the term 'vector graphics' refer to?

The term 'vector graphics' refers to images created using mathematical formulas to define shapes. Unlike raster graphics, which are made up of pixels and can lose quality when scaled, vector graphics use points, lines, curves, and shapes defined by mathematical equations. This allows for images to be resized without any loss of quality, making them ideal for logos, illustrations, and any graphics that require scalability. This mathematical foundation enables designers to create smooth, clean lines and shapes that can be easily manipulated and edited.

The other options involve different types of images: images composed of pixels refer to raster graphics, which are resolution-dependent; images captured by digital photography pertain to photographic images, typically rasterized; and images manipulated through graphic software can apply to both raster and vector graphics but do not specifically define what vector graphics are. Thus, the focus and definition of vector graphics lie specifically in their mathematical representation.
