Answer 1

Answer:

The Greatest Integer Function is denoted by y = [x].

For all real numbers, x, the greatest integer function returns the largest integer 

less than or equal to x. In essence, it rounds down a real number to the nearest integer.

For example:   [1] = 1      [1.5] = 1      [3.7] = 3      [4.3] = 4

Beware!    [-2] = -2      [-1.6] = -2      [-2.1] = -3      [-5.5] = -6
