Graphic Design EOPA Practice Test

Which graphic type remains sharp when scaled and is defined by mathematical equations?

Raster graphic Bitmap image Pixel art Vector graphic

Correct Answer:

Vector graphic

Explanation:

Staying crisp when you resize comes from using a vector-based approach. Vector graphics describe each shape with mathematical equations that define paths and curves (for example, Bezier curves). When you scale, the image is recalculated from those equations, so edges stay clean and sharp at any size. Raster graphics and bitmap images, by contrast, are made of a fixed grid of pixels; enlarging them spreads those pixels, causing blur or jagged edges. Pixel art is a type of raster image built from a grid of colored squares, so scaling usually looks blocky. Because vector graphics are defined mathematically and resolution-independent, they remain crisp at any scale.
