What are the domain and range of the step function with the equation below?
fx)=-3[x]

Domain are the values which x will take in a given function.

In case of given function x can take all real numbers will ultimately convert it to the  integer being greatest integer function.

example [1.01] = 1

range is the set of values of y. Here values of y will be multiples of 3 and all will be integers. Since, all real numbers will convert to integer by [x] . we have f(x) that y = -3[x]  

y comes out to be an integer and multiple of 3.
