Which type of graphic uses points, lines, curves, and shapes based on mathematical equations and can be resized without sacrificing quality?

• A. Vector graphic
• B. Raster graphic
• C. Pixel graphic
• D. Bitmap graphic

Answer: (A)

Graphics defined by mathematical equations use points, lines, curves, and shapes to describe an image. Because the geometry is stored with math, resizing simply recalculates the rendering, keeping edges clean and sharp at any size. That means no quality is sacrificed when you scale up or down.

In contrast, raster graphics store color information for each pixel in a grid. When you enlarge a raster image, the pixels become visible, causing blurriness or blocky edges. Pixel or bitmap graphics are examples of this pixel-based approach, which is why they don’t stay crisp when resized.

So the type described—scalable without losing quality and built from mathematical definitions of shapes—is a vector graphic.
