Is the given 3x3 matrix invertible? Justify your answer.

Also known as Step or Floor Function Yet another example of piecewise function

For all real numbers, x, the greatest integer function returns the largest integer less than or equal to x. Rounds down a real number to the nearest integer. Ex: [1] = 1 [1.5] = 1 [3.7]=3 [4.3] = 4

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