Answer
From the diagram, the domain of the given floor function is the set of all real numbers, $D∈R$, while the range of the given floor function is the integers $0$ and $±1$, $R= {−1,0,1}$
Work Step by Step
The graph of $y=sinx$ is just a wave function. Using this graph, we can plot the ceiling function.
As the sine wave function is periodic, the ceiling function would also be periodic. As such, we can just focus on one cycle of the sine function.
