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

The third graph (left of the bottom) represents  over the domain 3≤x≤6.

Step-by-step explanation:

The Least Interger Function is represented by .

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  .and It is also known as ceiling of x.  For example

So the third graph (left of the bottom) represents  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 ... ]

Hope this helps (Copied from the same question from someone else)

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
