Scalable graphics that use mathematical formulas rather than pixels are known as what?

Vector graphics are defined by mathematical formulas that create shapes, lines, and other visual elements, which allows them to be scaled to any size without losing quality. This is because the image is not made up of individual pixels, but rather consists of paths defined by mathematical equations that describe the shapes and colors. As a result, vector graphics are ideal for illustrations, logos, and other designs that require resizing while maintaining sharpness and clarity.

Raster graphics, in contrast, are composed of a grid of pixels. When these images are scaled up, they can appear blurry or pixelated because the individual pixels become larger and more noticeable. Bitmap graphics are essentially another term for raster graphics, emphasizing the layout of individual bits that make up the image. "Scaling images" is a general term that applies to both raster and vector graphics, but it does not specifically refer to how the graphics are constructed.
