Question

Which graph represents y=⌈x⌉ over the domain 3≤x≤6 ?

Answer 1

Answer: correctly is C

Explanation:

Answer 2

Answer:The third graph (left of the bottom) represents
`y=\left \lceil x \right \rceil`over the domain 3≤x≤6.

Explanation:

The Least Interger Function is represented by
`y=\left \lceil x \right \rceil`.

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
`\left \lceil x \right \rceil`.and It is also known as ceiling of x. For example

`\left \lceil3.4\right \rceil=4,\left \lceil5.6\right \rceil=6. \left \lceil4.4\right \rceil=5`

So the third graph (left of the bottom) represents
`y=\left \lceil x \right \rceil`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 ... ]
