Answer:The third graph (left of the bottom) represents [tex]y=\left \lceil x \right \rceil[/tex]over the domain 3≤x≤6.
Step-by-step explanation:
The Least Interger Function is represented by [tex]y=\left \lceil x \right \rceil[/tex].
The least integer function is a discontinuous function whose value at any number x is the smallest integer greater than of equal to x .It is denoted by [tex]\left \lceil x \right \rceil[/tex].and It is also known as ceiling of x. For example
[tex]\left \lceil3.4\right \rceil=4,\left \lceil5.6\right \rceil=6. \left \lceil4.4\right \rceil=5[/tex]
So the third graph (left of the bottom) represents [tex]y=\left \lceil x \right \rceil[/tex]over the domain 3≤x≤6.
[we can see all the value of x starting from 3 pointed at y=3 and for x≤ 4 are converging to y=4 which is represented by solid dot and so on ... ]
