How an image is represented mathematically?

An image can be defined as a 2D signal that varies over the spatial coordinates x and y and can be written mathematically a f(x,y). In general, the image can be written as a mathematical function f(x,y) as a matrix of values, comprising of rows and columns. The image f(x,y) is divided into X rows and Y columns.

Can array store images?
